I have a gateway machine (funky, Linux 2.0.30) with 3 ethernet cards. It has eth0 for the internal subnet which masquerades out to the world through eth1. I have another machine (dopey, Win95) connected through eth2 which needs to be the same IP as eth1. dopey needs to run some Windows authentication software and only needs to talk to the outside world.
IE. I want to redirect a select few ports from funky to
dopey so that dopey is the sole responder to those ports.
1) How shall I ifconfig and route my eth2?
2) How can I ipfwadm/ipautofw to achieve my goal?
3) Can I achieve my goal without patching my kernal?
Thanks for any help.
