Greetings All,
After upgrading from kernel 2.0.38 w/ slackware-3.4 to
kernel 2.2.16 w/ slackware-7.1 I have developed the following
routing problems.
Hardware -
eth0 - 10meg on net 192.168.0.0 i/f 192.168.0.1 subnet
255.255.255.128
eth1 - 100meg on net 192.168.0.128 i/f 192.168.0.130 subnet
255.255.255.128
>From either network I can use ipchains and surf/telnet/ftp/... on
each network to the ppp0 dialup connection. I cannot ping or
anything from eth0 to eth1 or back.

TIA - if other files are needed, I can forward.

Um, I don't see what this has to do with ipchains, but my guess is:
echo 1 > /proc/sys/net/ipv4/ip_forward
Rusty.

Hey Andy - haven't heard from you since work on a replacement linuxHQ (ahh

When upgrading slackware (not a complete reinstall) it doesn't replace you
rc scripts in /etc/rc.d. 2.2.x has a /proc entry to enable forwarding.
You need to echo 1 > /proc/sys/net/ipv4/ip_forward to enable forwarding.
Newer slackware does this in /etc/rc.d/rc.inet2.
I'm not sure this is your problem. If you installed slackware new without
upgrading this probably isn't the answer.
