Brendan,
I have done this for years, but for the past six months the ppp package has
been screwed up and will not pass the ppp session off to the dial in line.
Currently, I have this as my /etc/ppp/options file with the modem on ttyS1 and
the cable connection rounted through eth0:
debug
kdebug 7
crtscts
lock
modem
nodetach
lcp-echo-interval 30
lcp-echo-failure 4
lcp-max-configure 60
lcp-restart 2
idle 600
noipx
file /etc/ppp/filters
asyncmap 200a0000
proxyarp
login # Note there is a current dispute whether login will prevent the ppp
# connection from being established on some systems. Try with and
# without it and see what you get.
ms-dns 192.168.6.17
ms-wins 192.168.6.17
netmask 255.255.255.0
192.168.6.17:192.168.6.11
The last good working config I had was on a suse 10.3 box. Since then nothing
has worked on suse 11.0 - 11.1 or Arch. I'm still digging into the issue time
permitting.
