Remote Desktop type app with vpn AOKP rom issues

I have searched but couldnt find an answer, if I missed it please get me a link and close this thread.
Hey all got a quick question that I am hoping someone can help me figure out. This is all using the Prime with Jermaine's Milestone 5(AOKP)Rom.
1. I am using either Remote Dektop, 2x Client, or Splashtop Hd
2. Vpn setup using PPTP
My issue is I can connect to the vpn I have setup no problems, then try and remote desktop/2x client/ splashtop hd in to my works server(which is on 2008 r2) and I get an error that wont let me connect, it then times out.
I can use the same apps and a vpn setup on my phone HTC Sensation with Elegancia ics 3.6.5 custom rom and everything works like its suppose to, I can connect to the vpn and then use any of the apps to connect remotely to the server and im on no issues.
Is it that AOKP cant allow this or am I missing something, I really need this for work as I hate taking my freakin laptop home Any help would be greatly appreciated.!!!!

Changing the NAT settings.

Is there ANY way to change NAT setting that my phone is using? I've got a v. fast connection and want to use it for online gaming but the NAT type I have now (Strict) does not really let me do that. I've tried Barnacle Tether but it is not working for me... So, any suggestions would be really appreciated as this is important for me.

I believe you can't get open NAT on android. we do not have UPnP so no NAT

Port Forwarding

Hey,
I have a S3 LTE and im looking for a way to open ports on my phones modem.
Let me explain, where I live we have shockingly bad internet service so more often than not I tether my computer to my phone either wirelessly or via USB. So far so good, problem is when I play games online (Black ops 2 PC in this instance) my NAT settings are set to strict and people cannot join my party. If I use my normal home connection my NAT setting goes to open and people can join.
So im looking for a way to open the ports required by BOPs2 so other players can join my party and play in a group but I cannot seem to find a way to do this. My phone is rooted and im currently running CM10.1 Official nightlies.
So now im left with two choices, use my home connection and suffer with constant disconnections and poor speed or use my phone and have my friends play with me but not on my team.
I have no problems playing game, everything works, its just people can't connect to me and play as a group.
I have googled this but to no avail so im hoping someone here would have a way to do this.
Many many thanks,
Scott.
Opening ports and forwarding ports are 2 different things.
Please advise what your home router settings are in regards to the specific ports you need. Also please advise what ports you need.
Where are NAT settings showing as "strict"?
When running the game on PC, what does android terminal emulator output say for "netstat" command on the specified ports?

Thanks for the quick reply. When I use my home connection, I've just done it the lazy way and enabled DMZ.
I've tried using that app you suggested but I still have a strict NAT setting when using my phone.
The ports are (what Google is telling me)
Application: COD7BOPS External port: 3074 Internal port: 3074 Protocol: TCP/UDP
In addition, the following ports are required for Steam connections
Application: COD7OPS1 Port range: 27000 - 27030 Protocol: UDP
Application: COD7OPS2 Port range: 27014 - 27050 Protocol: TCP
The game itself tells you what your NAT setting is. Before I enabled DMZ my NAT while using my router was 'moderate' some of the time people could connect to me. Now I have DMZ on its changed to open and it works 100%
I haven't checked what the terminal is displaying but I'll do that when I get home.
Terminal may be important.
It may be your carrier rather than device blocking ports by the way.
I'll update this post once I get home and see what the terminal says. Yeah I know it could be my network supplier that's blocking it. I don't have a way to test that do I?
It's not a huge problem, it would just be nice too play with my friends in a party.
Rehardless, is what im asking possible anyways? Forwarding ports on the phones modem.
Thanks

Well the app apparently forwards ports. The port needs to be open for that to work though.
The only way to test if the port is open and if its the device or carrier, is by process of elimination. Lets see what netstat says first.
Great thanks for the help mate. I appreciate it.

I've been dealing with this problem as well, nevertheless with port 22, not related to gaming.
Hope someone can give a suitable answer for port forwarding!

[Q] changing Nat type while tethering?

Is there a way to change Nat type on device ( galaxy note3)? Basically I'm trying to tether my device to my Xbox 1, as is I can connect and tether my 360 and it works fine, but in the xb1 it connects but I see the Nat type is set to moderate and not open thus causing connection issues. I played with apn settings and was able to set Nat type to strict but not open so I'm under the impression it's dueable through specific apn settings. I do see fields in apn settings that list port, but I'm not that educated to know what goes there or if it's even possible. Any help would be appreciated
