I'm in the process of creating a firewall using the ipchains-system.
As it is now, it works with 3 ethernet cards. It does what it is
supposed to do (roughly):
- block incoming connections
- allow outgoing traffic
I've been experimenting with aliased interfaces but with no luck.
All rules with 'ipchains -i eth0 ...' works, whereas all rules with
'ipchains -i eth0:x ...' fails.
Is this a limitation in ipchains?
Kernel is 2.1.128/129 ... (compiled with alias support et. al.)
Kind regards,
Brian
