I am using demand dialing with pppd right now. I want to get diald
working so I can have different timeout periods for different
connections. I have been using telnet, ping, netscape, and ftp from my
linux box to test diald. I think you are right that my kernel doesn't
notice the need to renumber. With pppd and demand dialing, I
occasionally get messages like this in my logs, but never with diald:
Jun 7 10:41:38 debian kernel: tcp_v4_rebuild_header(): shifting
sk->saddr from 192.168.1.10 to 199.2.132.133
The README.masq file in the diald 0.99 talks about using the "ip-up" and
"addroute" scripts to help with masquerading. Perhaps these would help
with my case as well?
Here is the output of cat /proc/version, ifconfig -a, and route -n.
This first output is from the first diald connection, which usually
works, and was working in this particular case:

This is the output from the second try, which didn't work, giving
"Hostname lookup failure" and "network unreachable" errors:
