Description gnw 1998-12-29 13:34:02 EST

I've tried this with 3 different kernels, 2.0.34-36 and RH
dists 5.1 and 5.2 the problem persists.

entering: ipfwadm -F -p masq
works fine and masquerading is activated

entering something like:ipfwadm -F -i deny -S 204.0.1.2
will fail with: ipfwadm: setsockopt failed: Invalid argument

I have copiled a 2.0.35 kernel on an intel box and had no
trouble getting ipfwadm to work as expected.

Comment 1 Jay Turner 1998-12-31 17:39:59 EST

This may sound like a dumb question but do you have IP_Firewalling and
 IP_Masquerading enabled in you kernel config and properly recompiled
the kernel? The kernels ship with 5.2 may have these disabled by
default.

Comment 2 gnw 1999-01-19 18:38:59 EST

Yes, I have compiled in all the appropriate kernel parts.
the Masq, and forwarding are working perfectly except for the inability
to change the non-default rules.

Comment 3 David Lawrence 1999-04-08 13:26:59 EDT

Could not get this to fail on a test lab machine with a stock install
of 5.2
