In masq can I Eth2 eth0:!192.168.1.3/32 Eth3 192.168.1.3/32 Then somehow with routing Route add default 202.x.x.x. (my eth2 address) Route add default 203.x.x.x (my eth3 address) src 192.168.1.3 Any clues? Also .. can How do I achieve this: In rules REDIRECT 80!eth0:192.168.1.3/32 8080 - !192.168.1.0/24 (in human readable format) Redirect everything on port 80 to port 8080 except if the source is 192.168.1.3 or if the original destination is 192.168.1.0/24
