Hi list After a reboot of my RedHat mashine, the NAT part of Iptables stop working. I get: "iptables: Invalid argument" when using snat. My snat rule look like this: $IPTABLES -t nat -A POSTROUTING -o $EXT_INT -j SNAT --to-source $EXT_IP I have made all netfilter stuff as modules. #lsmod ip_conntrack_irc 4336 1 (autoclean) ip_nat_irc 3440 0 (unused) ip_conntrack_ftp 5520 1 (autoclean) ip_nat_ftp 4240 0 (unused) ipt_ah 1080 0 (unused) ipt_esp 1112 0 (unused) iptable_nat 22040 2 [ip_nat_irc ip_nat_ftp] ppp_mppe 24088 0 (autoclean) bsd_comp 5464 0 (autoclean) ppp_async 9440 0 (autoclean) ppp_generic 24508 0 (autoclean) [ppp_mppe bsd_comp ppp_async] slhc 6740 0 (autoclean) [ppp_generic] ipt_LOG 4152 1 (autoclean) ipt_REJECT 4024 1 (autoclean) ipt_state 1048 5 (autoclean) iptable_mangle 2776 0 (autoclean) (unused) ip_conntrack 28296 4 (autoclean) [ip_conntrack_irc ip_nat_irc ip_conntrack_ftp ip_nat_ftp iptable_nat ipt_state] iptable_filter 2412 1 (autoclean) ip_tables 14872 10 [ipt_ah ipt_esp iptable_nat ipt_LOG ipt_REJECT ipt_state iptable_mangle iptable_filter] Any hints??? I have tried to recompile iptables - but nothing seems to work - I know it did before the reboot. Only thing that has been changed is a static route being enabled, but this shouldn't make iptables complain:( Thanks a lot
