problem with GPRS connection to outside world (ppp)
I have installed a MultiTech USB MultiModem GPRS on Slackware 10.2 with a 2.6.12 kernel.
I am able to install the modem's driver into the kernel and then dial up to the T-Mobile server, obtaining (I think) an IP address, but I cannot get traffic through the modem. I have tried pinging out through the modem (bash# ping -I ppp0 <address>), doesn't work. I also tried pinging the modem's IP (208.54.147.71) and ssh'ing into the machine through that same IP to no avail.
I have also tried this same set of actions with first killing the ethernet interface (bash# ifconfig eth0 down), with exactly the same results. Below is the command I use to call the PPP daemon and also the ifconfig and route states. Any help would be greatly appreciated!
