linmodem, connects to ISP, but can't ping past gateway.
I have a lucent linmodem. In a HD install of knoppix (debian), I have gotten the linmodem working using a plethora of different howto's and posts.
Unfortunately, the driver is a not-so-free driver that only lets me connect at 14.4 (and I can't see that I want to pony up 35$ for the extra speed, after all, 90$ will buy me a HW modem, which I thought I was getting when I bought the first thing... aargh).
Getting back to the problem, I can connect to the ISP (I can listen to the connection happen through my sound card) and I can manually get to the ISP text login, successfully log in, and start ppp (yes, I have also set up scripts to do this).
After I am connected, ifconfig shows the ppp-line. I can see the local and remote IP's. I can ping either end. I have the DNS servers correctly entered, and I think I have my routing table being generated properly as I connect/disconnect. But when I try to ping anything past the other end of my serial line connection, I don't get an answer. I have spent quite come time trying to fix this already... I'm going to try the steps in the diald howto, but I am somewhat doubtful that this will solve my problem. (since I have already set up ppp-on/off by hand and tried going through several other ways of establishing the connection.)
