I'm using iptables 1.2.9 and kernel 2.6.0-test11.. I may be doing something really stupid but if I do this: iptables -t nat -A POSTROUTING -m physdev --physdev-out eth1 -j SNAT --to-source x.x.x.x I get: iptables: Invalid argument but if I just use ACCEPT as the target it works fine, although doesn't do what I want.. I've got the bridging an physdev options turned on (otherwise I couldn't use the ACCEPT target).. Is this a bug, or am I misunderstanding something? -- Andy Loukes http://www.navaho.co.uk/
