netfilter/iptables bug ?
Hi all...
I'm trying to do NAT from a internal eth1 to external eth0 (connected with a cable modem). Every doc I read says I should do:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
But I just keep getting:
iptables: Invalid argument
Kernel: 2.4.21-pre6 + -pre5-aa. iptables 1.2.7a.
Modules loaded:
ipt_state 1080 0 (unused) iptable_mangle 2776 0 (autoclean) (unused) ipt_MASQUERADE 2296 0 (autoclean) iptable_nat 22136 0 (autoclean) [ipt_MASQUERADE] ip_conntrack 26848 2 (autoclean) [ipt_state ipt_MASQUERADE iptable_nat]
Is anybody aware of any obscure bug ? What does fail ? I have read reports, for example, of this same command working on RH 7.2 and faling the same way on 7.3 (I use Mandrake 9.1).
Any idea would be appreciated. TIA.

Recompile iptables against your new kernel.
A major NAT patch (newnat) went into 2.4.20 which changed a lot of structures. A recompile against a >= 2.4.20 kernel will get it working again.
I suggest that you post further mail about iptables-problems to [email protected] as that's where you are most likely to get help.

Thankyou very much.
Sometimes I doubt if this is a maling list or an IRC channel ;))
