I would like to do the following, and want to know if anyone out there can identify any potential pitfalls of this configuration. (for the record, I think this wil NOT work).
I want to use 2 different hardware firewalls over the same Internet connection. Specifically, I want to run a PIX 506 (that has a VPN tunnel with our Mexico operation) and I want to run a Watchguard Firebox X50 (that runs a tunnel with our China operation) over our new Sprint 3 meg connection. Currently, each firewall lives on it's own separate connection.
Potential issues I see involve redirected services, like inbound Terminal Services access, and SMTP. for example, if our router is22.214.171.124, and the PIX is .2, and the Firebox is .3, will both firewalls try to answer if our internal Exchange server is .4?
