• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description mats pettersson 2003-04-08 17:24:34 UTC]

after emerge rsync; emerge --update world; on 030406 recompiled latest kernel 
2.4.20-gentoo-r2 with iptables support and apropriate iptables modules 
including ipt_MASQUERADE rebooted and my nat routing stopped working 
investigated this some more and i get the following when i try to insert this 
simple MASQUERADE rule

bash# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
 
it gives the following error code:
iptables: Invalid argument

emerge sync 
emerge -C iptables 
emerge iptables 
 
Let me know if the masq works after that.
