Hi everyone!
I'm having a very strange problem with getting pppd to work for outgoing
connections. I have two ISA modems installed, on ttyS1 and ttyS3. I have no
problems on ttyS1, but on ttyS3, I cannot ping the remote server - I connect as
usual, get assigned an IP, etc. but I still cannot ping anything (using the IP
address)! The connection shows up in ifconfig. Using minicom, I can dialout
and connect to remove systems with both modems and have no problems, using the
same configuration. I'm also running mgetty, and have no problems receiving
faxes, etc on either modem. I've tried switching the phone lines too. Does
anyone have *ANY* idea of what could be the problem or how to further
investigate it? I copied all kinds of info below.
Any help would be greatly appreciated. Thank you!
