3G router configuration for internet access

Hello, i have a question plz regarding the 3G routers configuration. 

 

I am well aware of the normal 3G configuration using GRE tunnels to connect a branch to the HQ, but what about using the 3G router to connect directly to the internet? I have a already a SIM card with an APN that has internet access, but what about the rest of the config? Will I need to configure GRE tunnels? But what will be the destination? 

 

Any help would be great, thank you.

Hello,

 

with a 3G connection to the Internet, you do not need a GRE tunnel, but you need NAT. Basically the cellular interface is treated as a 'regular' WAN interface.

Which router model do you have ? Post the config, and we can fill in the necessary bits and pieces...
