perhaps someone can tell me if it is possible to use the Fastrack Supreme as an internet gateway. I have a client on the serial port of the modem which I need to connect to the internet over GPRS. As long as there is an ip connection between the uart of the client an the modem and another ip connection on the GPRS site, I need to NAT/masquerade/route the traffic between these two nets. Is the Open AT OS capable of doing this or the WIP plugin?
CLIENT <–> Fastrack <–> Internet
CLIENT: PPP Server
Fastrack UART: PPP CLient and Internet Gateway for the CLIENT
Fastrack GPRS: Internet
I hope you understand what I wanna do. Any help is appreciated.
What I programmed:
I used a bearer for the uart and a second bearer for the gprs. There is a flag WIP_BOPT_IP_SETGW which I set TRUE for the GPRS bearer and FALSE for the UART bearer. I guess that this option sets the default gateway which is used for all external networks, aka the internet.
