I appear to be having an issue getting two separate NICs setup and working correctly as external interfaces. The intent here is to use one external address for all regular traffic, and accept all Outlook Web Access traffic on the second interface. The NIC cards are installed on the system, detected and appear to be functional. We use DHCP to obtain our static IP addresses on each interface (limitation of the ISP – same limitation that prevents the use of IP Aliasing). While just the primary NIC is green-lighted and running, everything runs as expected. As soon as I activate the second NIC and it acquires the correct IP address from the ISP, I lose all internet connectivity.
Are there some sort of issues with having two separate NICs each having an external address?
A little bit more info: Connection map -> DSL Modem ---> Hub ===> NIC1 & 2 (Firewall) Integrated NIC ---> LAN.
"-" one Cat5 cable
"=" two Cat5 cables
Thanks for any ideas!
