Accessing a network via 3G/4G internet dongle.

[FieldSupportEngineer]

I currently have 4 individual sites that i am contracted to maintain. 2 of the sites have full servers and network connectivity and the other 2 sites are running via 3G/4G internet dongles through an APN. Ive been forced to reduce my travelling and need to find a way to have remote access to all my sites. How and what do i have to do so that i can remote access my sites with network/lan connections via my internet dongle and visa-versa. Ive tried teamviewer ( which works perfect when to im on the network and connecting to another pc on the same network or 3g to 3g connection) but struggling to find a way to connect via network to 3g and visa-versa.

The network being 3g 4g by itself makes no real difference. The problem with many of these networks is you do not have a routable ip address and the shared ip can change from time to time. This pretty much prevents any form of inbound connection to these sites.

Things like teamviewer should work because both end machine go to a common central server. This tends to not be secure because the company running teamviewer can see everything and if they were hacked or a dihonest employee you run quite a risk.

Now if your end was a actual routable IP address you could set up vpn from the remote sites and if they are initiated from the remote end they should get through the nat without problems.

I know with the 3G/4G you might not be able to get static IP addresses, let alone the fact the carrier might be blocking certain ports on their network as well. I would say your best bet might be teamviewer or logmein or gotomypc. I use teamviewer and as long as my end user has a internet connection I have been able to access their computer.
