I'm tryin to use the netmap argument with iptables, and when i try using the example, which even though i don't have those ips, should still work i get the following.... root@test root]# iptables -t nat -A PREROUTING -d 1.2.3.0/24 -j NETMAP --to 5.6.7.0/24 iptables v1.2.8: Unknown arg `--to' Try `iptables -h' or 'iptables --help' for more information. [root@test root]# I'm running RH 3.0EL, 2.4.22 kernel w/the current patchomatic installed, use the "base" option. Any ideas? Thanks in advance, Aaron P. Martinez
