Connecting the Raspberry Pi to a fixed IP active DHCP server (wi-fi) and 3g network using a dongle simultaneously.

Question

I'm impressed with the discussions I've seen here over the raspberry Pi. I'm a software architect and developer I would like to contribute where I can and of course ask for help when I'm at the end of the tunell

Ok, i'm new to the Pi and I need to know if it is possible to connect the the Raspberry Pi to a fixed IP active DHCP server (over wi-fi, no internet) and to a 3g internet network simultaneously.

Now both are working independently, that is, it is possible to establish a wi-fi connection using the WiFi edimax adapter and connect to the internet using 3g modem. But, I need to send and receive packets over the (fixed IP to fixed IP) dhcp and at the same time all other applications on the Pi using internet should still work.

I would really appreciate any kind of direction .

(The PI is running raspbian OS)

Yes is the answer each interlace is doable and no doubt you'll see examples of each been used individually.

Each will be seen as a separate device and have separate network configuration so you can send data to either one or both no problem you will need to configure the routing however if the defaults are not to your liking.

Assuming that the defaults don't work for you , you'll need to set the routing to send the data for the local subnet to the WIFI( I assume that the WIFI LAN is all on it's own by the sounds) then use the 3G as default for all other routes.
