I can imagen why you want to go back in time by compileing a kernel which
is lower than what you have, 2.0.30 was renouwen for a big memory bug + a
lot of others. Anyway thats your choise.

Oops stop here, what about make modules and modules_install.

Well whatever PID 933 was it caused the above problem, that "should not
happen".

If the compile had failed then you would have seen an "error" from gcc and a
few warnings beforehand, now i presume you did not get any otherwise you
would have seen them right?.
The place to see if ip_forward is compiled in "and" turned on do;
cat /proc/sys/net/ipv4/ip_forward
on = 1
off = 0
If the file is not there at all then you did not include IP_FORWARDING in
make config, you can also check your options in
/usr/src/linux-2.0.30/.config {use 'less'} to read it.
I rather think you forgot to do 'make modules and modules_install' !!!.
