Webserver visible from 2 ISPs?

Hi,

I would like some advice on how to perform what first appeared (to me) to be a simple task

I have a mailserver which I want to make accessible from 2 different ISPs

Code:


  ISP1                    ISP2
   |                       |
  FW1                     FW2
   |                       |
   -------------------------
                |
            MailServer

I have 2 firewalls (IPCop) which I would rather not mess with too much, I don't mind putting 2 NIC's into the Mailserver box if that will help.

The essence of the problem is that inbound packets reach the Mailserver from either ISP but the outbound packets go via the default route setup on the Mailserver and so don't go out via the same ISP that came in on.

I can set dual default gateways on the Mailserver but that doesn't fix the problem because the outbound packets still don't know which gateway to use!

Many Thanks!

Sil

P.S. the Mailserver is running RH7.3 if that makes any difference
