[Q] Android VPN - EVO 4G Q&A, Help & Troubleshooting

First of all, I would like to thank all the developers on the site for some outstanding work. I have been trying out some of the great ROM's found here and I would just like to thank all you guys for all the hard work put into your Rom's. I am really appreciative of all the great information found here.
I have an issue I have been working on for a bit, and I was wondering if I can get some of you to comment or try to figure this one out.
At my office, we have a RV-120w Cisco firewall/router. We have a small office, and this unit has worked great in securing my server, but allowing some of my Project Manager's to remote in via IPsec. The remote VPN works great from desktop to router. We connect to the router, and then RD to the workstation.
The issue I have, is I cannot get an Android device to connect via IPsec. I can see the unit talking to the router (from the log), but the connection times out stating "Could not find a configuration".
I have tried the Cisco boards and have gotten no where. If any of you have an idea I could try, I would greatly appreacite it.

Hey,
are you making sure everything is registered right on both sides? & it might be a rom glitch to. Try flashing a differnt rom making sure you have all the right info and try again. and If that doesnt do it Idk man Im sorry :/

L2PT only with IPsec is supported.
So you should be running IPsec and L2PT with the VPN. Probably should look into the OpenVPN installers for the android phones (i can help with that).
But my experience is that our android phones are finicky with the protocols you use.

Cisco again........
I regualrly visit forums and blogs for some VPN news, what i see the most are people having issues with vpn settings in general and specially cisco, cisco vpn routers have been rocket science to learn and use efficiently,

WM6 Internet Sharing Port Forwarding

hello everybody,
i´ve checked the wikis and searched through the whole forum but did not find anything related to that. my question is:
my notebook is connected via the internet connection sharing - everything is working fine - but i can´t use some services because i need to forward the ident port (113) among a few others for that.
so, any idea how i can do that? (if possible at all).
any help would be greatly appreciated!
I think port forwarding might be a bit hard.
First thing you need to check is what IP your Tytn gets from your ISP. If its in the private IP range
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
then its not going to happen. Your ISP(ie your telco) is NATing you further up the chain and they are the ones who needs to forward the ports for you.
It doesn't really matter what IP he gets from his ISP - the phone is already NAT'ing the connection. Unfortunately I don't think it's possible to forward ports with the phone.
Ofcourse it does. If his phone is getting a public ip there im sure there is a way to forward the ports.
But if his ISP is doing the NATing then there is no way.
hmm, so you guys think it´s already time to give up hope?
The same question.
I need port forwarding for utorrent client...
When it was WM5, there was a Modem program, so we can easy create and ue dial-up connection on PC! and PC gets real IP from cellular provider...But now WM6 works as Router and PC gets fake IP from mobile device(mobile gets real ip from cell provider)
And we can't do anything
Dmitry: Just because I'm curious: what network you are using and what is the ip subnet you are provided by the operator? So never seen in even one operator, that would provide me with external IP.
Does this do what you are looking for?
I found this app.

VPN Software

Anyone have any experience with a working VPN client freeware or not on the TP2?

Google is your friend..
http://www.google.com/search?client...reeware+windows+mobile+vpn&btnG=Google+Search
Google is indeed one's friend, and I expect the OP has done many searches exactly like the one above, as I have.
However if you go beyond looking at the google headlines you soon discover that none of these solutions is in fact freeware, as he had requested.
So far I've spent many many hours trying to find a decent winmo IPSec client, free or reasonably priced, and my conclusion so far is that there isn't one. None I can find are free, and the ones that don't cost ridiculous money all have serious functional issues and/or stupid design decisions like requiring you to run their PC version to be able to create security profiles for the mobile one.

Actually I see the OP in fact asked for free or otherwise, but they also asked if people had experience with such things, not just were they around.
What about
http://www.zeroshell.net/eng/openvpn-client/#OpenVPN-Windows-Mobile
OpenVPN is extremely nice, but it only works against OpenVPN servers. If you're trying to do IPsec VPN, OpenVPN won't help.
I have done a google search but the results are so generic. I figured people using some of the best WinMo phones would have tried some of these.
I tried searching XDA but did not really come up with anything.
Open VPN probably will not work for me unfortunately.
I need something compatible with cisco.
There are numerous kinds of ipsec, you'd need to tell us which ones your cisco device supports. I've used the openvpn client on the tp2 to some success.
This page has always had the most info in ipsec, I recommend checking some of the various guides on it.
http://www.jacco2.dds.nl/networking/openswan-l2tp.html#No_MSCHAP
Here's a quote from it:
Windows Mobile and Pocket PC 2003 ship with a built-in L2TP/IPsec client. Requires MS-CHAP support in pppd.

I think it's relatively easy to connect to Windows based VPN servers running MS software but I'm not so sure how well it fares with Cisco kit. I'd be surprised if the cisco box didn't support the l2tp protocol, I think it's very common. I believe the incompatibilities come about from the authentication part, which is what the MS-CHAP support mentioned above refers to. Further down the linked page it mentions Cisco kit.
I use the Bluefire Security Technologies Mobile Security VPN 2.7.5.706 .
However it seems Bluefire is out of business...
But it works perfectly for establishing VPN connections to Cisco routers and PIX/ASA's, even with token authentication.
Previously I used the Bluefire client for a few years and it was the only reliable one for Cisco concentrators, but as you said they have gone out of business now.
Also recently I've found I can't get the Bluefire client to work with some of the newer roms I've flashed (NRG etc.), perhaps changes in the newer winmo network stack or something.
I have tried the others and they are expensive and to be honest too much hassle to set up and have lousy error reporting to work out what you did wrong, I've wasted days, literally.
If you have the newer Cisco VPN kit they have dropped IPSec and gone for SSL VPN instead and do their own client for Windows Mobile which is OK.
rdleeuw what rom are you using, stock?

I'm using the stock ROM 1.19.401.0 (51489) WWE with Radi0 3.44.25.27 .

[Q] Why does the VPN suck in Android?

Does anyone know of a ROM in which the PPTP VPN actually works? I've tried 6 or 7 different roms today and have yet to find one that works. Is this a Google issue, or something else? Surely some developer must have tested this function and can speak to whether or not the VPN works. I recall that in WINMO only a few roms had reliable VPN functionally, Mighty Mike and Silence come to mind. Just to be clear...here is what is generally happening; the VPN connects without a problem. The RAS server displays the connection and shows packets in and out. Some roms will not route one packet properly to the device. Others will appear to work great, pinging remote resources, but as soon as you try to do anything else, i.e. RDP, the connection crashes.
Thanks

Connect to Ad Hoc without internet through Wifi

Hi everyone!
I'm having kind of a special problem.
I'm an electro acoustic musician and finds the Desire a lot of fun.
My new project is to use its accelerometer etc and for that I need to connect it to my Mac running OSX 10.6.5.
The issue I'm having is that my network (campus ish) won't allow me to open any ports. I don't think it's a good idea to hack it, so my next idea is to create a network between my Mac and my Desire. This network won't have access to the internet.
It also has to be via Wifi since the app I'm using only allows communication through wifi and my java skills aren't good enough to edit the apk.
I therefore run Oxygen 1.0 (GREAT rom btw) which is supposed to accept ad-hoc, and my computers own network does show up when i browse it in my phone.
The problem is that it dosn't connect since it isn't given an ip. I imagine there has to be a solution to this and I'm just not seeing it. I'm also thinking it could be an OSX issue and not really a question for this forum, but I'm pretty sure it should be possible to just make the phone not requesting an internet ip.
I've tried to set a static IP but this won't work ether.
Does anyone have a clue on how to do? I'm quite desperate really. Been searching for a solution online for quite some time and I haven't found the right one. Probably because most people using ad-hoc want it's phone to connect to the internet and therefore not having my kind of trouble. Unfortunately I have no way of connecting my computer to the router with wire since the router is about 400 meters away. Once of corse, but i really need a wireless solution in the long run.
Thanks!

L2TP VPN Doesn't work on native MIUI 11.0.3

Hello everyone,
as noted in the title of this thread, I cannot connect to L2TP/IPSec VPN Server from my phone (Redmi Note 8 Pro, running MIUI 11.0.3 stock).
I've done extensive troubleshooting and appears that phone never even contacts the server. When i configure everything and toggle the VPN, it will try to connect but never does, and then times out.
I'm watching the logs on the server, nothing appears.
I'm watching tcpdump on the server, no packet is even received from phone.
I've connected to WiFi network from i which i know i can connect to VPN (for example from PC or my MikroTik router) and it cannot even connect from that network.
I've enabled packet sniffer on root MikroTik router to sniff the packets, filtering MAC address of my phone, and guess what... When i click on VPN, it doesn't even try to connect to VPN serever. VPN server IP address doesn't even appear on sniff.
I'm wondering why is this happening, is anyone else having issues with L2TP/IPSec VPN? How do i inform Xiaomi of this issue since I've placed couple of feedbacks back in the day, never received an answer and those issues still persists so i don't even thing they are reading the feedback that is sent to them from phone app.
Hoping to get to the bottom of this!
Any help would be greatly appreciated !
Any chance you can try the OpenVPN app? I used to have an issue with my old phone where sometimes it would say connected but it wouldn't be. With the rn8pro, OpenVPN works every time.
Edit: try posting on the Mi forums for a better chance of a response from someone at Xiaomi
https://c.mi.com/global/forum-2234-1.html
Might not just be Xiaomi....https://github.com/SoftEtherVPN/SoftEtherVPN/issues/571
I would hate having two VPN servers installed at the same time. There are times when i want to connect my root mikrotik router to VPN server i question to forward all web traffic via VPN, unfortunately, OpenVPN support is very limited on MikroTik , there are new cipher suites missing and with new OpenVPN servers in place it's impossible to connect tik to OpenVPN.
I know however that OpenVPN app works great with android, but it's weird that native L2TP doesn't seem to be working at all.
I could fall back to PPTP maybe. Both Android and MikroTik works flawlessly with PPTP. But... It's PPTP..
Thanks, i will try posting to Xiaomi forums as well.
