Hi all,
I've a routing problem. I'm setting up a router based on debian (kernel
2.4).
I need to setup routing to export an ftp service (ftp server is in dmz)
to 2 wan (both).
I setup prerouting ad forward rule with no problem.
The problem is that reply packet use default gateway (default wan) even
though they are enter using the other wan.
I solved it marking packets in input from the dmz iface and force to use
another gateway (iproute2), but in this way I don't export ftp service
on default wan.
how I can setup routing to export ftp service on both iface?
Thanks in advance,
Fabio
One way to do this:
1. Assign 2 private domain IP addresses to the ftp server and listen to
both for ftp. IP1 and IP2
2. Map one IP each for WAN address. WAN1>>IP1 and WAN2>>IP2
3. On the Linux machine, set policy routing based on src IP of reply
packet i.e. src IP1 goes thro' WAN1 and src IP2 goes thro' WAN2.
