Tether to Replace Home Internet - Closed Port Issue - Verizon LG G4

I want to start out by stating this may be a general Verizon issue, but was hoping to get some input here first on the issue I'm facing.
My situation is that I want to replace my home cable internet with my LG G4 via tethering. I installed a wireless card on a desktop computer, connected it to VZW network via wifi tethering from the G4, enabled connection sharing on the desktop computer, then plugged an Ethernet cord from the desktop into the WAN port of my home firewall/router. This worked perfectly, giving the rest of my home devices internet via my 4G connection!
However I have some externally facing services, such as VPN and RD Gateway that don't seem to work over the 4G connection. I've done some troubleshooting and have a suspicion inbound communication on these ports is possible blocked by Verizon.
Sidenote - these services are configured with a Dynamic DNS provider - the external IP address does change correctly when I cutover to 4G service.
I reverted my home network back to the way it was and started focusing on the G4. I played with iptables (I'm rooted) with no luck. I attempted to open ftp connection to the G4 on port 2221 with no luck (using FTPServer & FTP Server Plus apps), still nothing. I changed the port a few times to something random > 1032, still nothing.
Does anyone know if Verizon is blocking external inbound communication, or possibly if there is something on the G4 I'm overlooking?
Any information is appreciated! If I can get through this issue, I can cut my ties to Comcast!!

Everything I've read in the past says that Verizon does not allow inbound TCP connections to your device via LTE. I'm guessing that the same applies to other wireless providers.

Reverse USB tethering achieved (kinda)

Hey guys,
I'm stuck in the middle of nowhere with no phone coverage, a satellite internet link, a laptop without WiFi (ethernet to sat modem), no WiFi routers, and my HTC Desire, and having just flashed my Desire with some sweet, sweet Modaco goodness, I wanted to start reinstalling everything
So, as the only way I could get any sort of link between my Desire and my laptop is via USB, I figured I'd give it a crack. Situation:
- Phone in USB tether mode
- Laptop tethered to phone via USB
- HTC USB tether interface bridged to local area connection on laptop
- Laptop setup as PPTP VPN server (standard WinXP "Incoming connection")
- VPN established from phone back to laptop
End state: I can browse the internet, on the phone, via the laptop, via the satellite
However, this only works through the browser. All other software on the phone is convinced it has no data connection (which by all reports, it doesn't. no GPRS, no 3G, no WiFi), and as such, things like Marketplace, Mail, basically all apps except for the browser don't work.
I'm not after a solution or anything, I'm going back to civilization tomorrow, I just thought you guys might wanna know. I know there have been a few threads of people attempting to achieve this.

Just without having a detailed look into it.
You have to make sure you route absolutely everything throw your VPN connection.
At the moment it looks like you only route port 80 for HTTP.
Android market uses 5228 if my very quick google search is correct.
Never used VPN on Android but the problem you desribed is well known for "wrong" VPN settings.
Hope that helped a bit.

[Q] Portable Wi-Fi hotspot

Hello,
I want to use portable Wi-Fi hotspot on my phone to connect to my laptop in places where public wi-fi is not available, or to connect to two computers to each other. And it seems to be working.
But I have a problem. I do not want to use mobile network to access Internet for those computers. I want only to exchange data between phone and computer, or between computers themselves.
But every time I switch on hotspot, 3G connection switches on automatically, even if it is switched off on purpose. I know this is intended use of hotspot, but I have a question:
Is there a way to prevent phone switching 3G network on in wi-fi hotspot mode, or just preventing data traffic over 3G?
Or I am missing the point completely?
The application is not intended for such usage; all it does is route traffic between connected wlan-clients and the carrier's apn. The phone itself has the ip-address 192.168.1.1 during this setup, but it is not listening on any ports that would be useful for your setup (ie 'cifs/samba').

I do not know if I do understand you but here are the facts:
I connect two dell laptops to portable wi-fi hotspot on my wildfire s:
one is : 192.168.1.135
other : 192.168.1.185
I can ping one from another. If I share a folder in one (.135) and go to others(.185) "Search for computers or people" I see all files in shared folder and can do all the usual operations over them (edit, move...)
Also if I install Remote Web Desktop from Market on my phone I can access phone through web interface.
In a word, I can do all things as on "normal" wi-fi network ( and I promise it is the only network around here ) except all the time I have 3G switched on. And I do not want to do that because I see my network data traffic going up.
So, as I see things, my only problem is unwanted 3G traffic.
Help?
Ah, but you did not mention that you had installed a seperate application to open up a port for the webinterface.
This however does not change the intended usage for the mobile wifi hotspot application!
hey...you can try this:
1. go to your mobile network settings
2. create a new APN, a dummy one
3. set the new APN as default
4. launch your wifihotspot
I did not test it with 2 pcs but, when u launch wifihotspot, 3g no longer comes on and my pc still connected to the wireless network without any problems.
Let us know your results
Cheers,
Hey,
I ran more test on this issue. The previous posted solution works like a charm.
I was able to use the wifihotspot as a wireless access point:
1. 2 or more PCs can communicate with each other (browse folders)
2. If one of the PCs has internet access, it shares to the rest of the PCs
3. If one of the PCs has an ethernet connection to a server, all other PCs also get connection to the server
For 3. to work, you will need to brigde the local area connection with the wireless connection on the PC that has cabled ethernet connection. Also browsing folders will work only if you use \\server ip (\\servername does not work).
I will try getting DNS access via the hotspot later.
Hope this helps

[Q] evo hotspot tethering and dd-wrt client bridge

This has been posted before, but I have found no solution in the thread.
As a network backup if/when internet fails me, I need to use the evo 4g to serve as the host for my client bridge (netgear with dd-wrt).
I've been using the client bridge successfully to connect to my Linksys router across the apartment.
I have to have a hard wired connection for my voip phone I use for work.
I match all the encryption, channel, ssid, etc. as I do for my normal network, but when I try to change everything over to match the cmod hotspot (not the wireless tether app which I have nothing but trouble with), it never works. All wired connections get a 169 IP from the router.
Google says that it needs to be in infrastructure mode, and it appears cmod7 uses that. I've tried a vast amount of different ssids, encryption methods, rebooting, etc.
Any info would be greatly appreciated. Does a different rom work better for this method, or do I need a different wifi app besides the one embedded in cmod7?

I don't think the router is giving you 169 IP addresses, those are a default random IP address that the Windows TCP/IP is assigning itself by default, that was useful back in the workgroup and hub days before the internet. I am researching this for future use, and will check back.

S4 tethering to a Draytek router

Anyone know how I can attach a Galaxy S4 mini to a Draytek 2820n router?
I'll give a bit of background that might explain why I'm trying to do what I'm doing.
I'm a heavy internet user. I need to download medical image files that are 300MB at a time on a frequent basis, as well as wanting to do usual downloading from iPlayer, Sky etc, plus app updates and all the usual keeping computers up to date. I live somewhere that I cannot get a decent ADSL connection (download speed is about 256Kb/s) never mind fibre. However, do have a good 3G (HSDPA) connection with three.co.uk. Have a Draytek 2820n router so I can use a 3G dongle via the router's USB so in essence the whole house has a fairly rapid internet connection. Only problem is that three's mobile broadband plans limit you to 15GB cap per month.
I've got a Galaxy S4 mini on monthly contract which gives unlimited (All You Can Eat) data and allows tethering.
I've been able to successfully connect wifi devices to the S4 via wifi tethering and use the internet but it's a pain having to switch wifi connections if say I want to control an XBMC server on my LAN, for instance. What would be ideal is to have the router distribute the S4's internet around. I can't just put the SIM in a mobile dongle as three have a way of blocking that (something to do with IMEI recognition) and I don't want to risk trying it.
Anyone got any ideas how I might be able to go about this. The Draytek router has various settings you can put into the 3G setup - I've attached a screenshot. I've tried various things but nothing works and I'm not sure how to access the router's debugging output. I set the S4 with USB debugging on in the developer settings. Wondering if there is something I can do that is fairly straightforward on the S4 so that I can try some generic dial string settings on the router to see if that works. I'd read something about putting the S4 into USB Kies mode but I don't seem to have that option.
My other thought was I might be able to leave the S4 in wifi tethering mode and somehow bridge this with my router but that would probably screw up my LAN DHCP assignments as I'd have to switch the router DHCP off and then I would be limited to 10 connections.
Sorry it's a bit long and complex. Any thoughts anyone?

Connect to WPA2-Enterprise wifi

Is there any way for the fire TV to connect to it? My university uses it, and I was wondering if I could connect, but the access point is not showing up
Can´t look now because I´m not at home but wasn´t there a setting for a manual AP setup where you could enter the SSID by yourself?
Some organizations may keep a second network available for legacy devices like printers, XBoxes, and older machines. You can check with your university's tech support to see how you can add your device to the list of allowed access for that network.
This isn't a guarantee that this network exists for you, but most enterprise and even some residential-grade equipment have this capability.
Otherwise, you might be able to find a router or range extender that can understand and connect to WPA2-Enterprise to work around this. In a pinch, an old laptop with two wifi cards or a wifi Ethernet port should suffice.
Or you may want to scrap wifi and run an Ethernet cable to your dorm's jack or personal switch.

Thanks the responses, but neither of them works well for me. there is a secondary unsecured wifi network, but it is just too slow to use, especially for streaming videos. I sideloaded a wifi APK onto it, and the networks DO show up, but there is no way to enter the login information (you need both a username and password.) Anyone know of an app that can do that?
