Hi gurus,
I have one Pix Firewall with (Internal and External NIC) and one Microsoft
ISA proxy server with (Internal and External NIC).
Tow VANS, VLAN 101 for Pix and ISA Proxy server VLAN 102 for all of my
clients.
Both Pix and ISA Proxy internal NIC are connected to Cat 3750 layer 3
switch.
I am using Pix as firewall for protecting Email server which is located
inside of my internet and its part of VLAN 101, and Emails server's default
gateway id the IP addresses of VLAN 101.
I have already defined the following in CAT 3750
ip route 0.0.0.0 0.0.0.0 192.168.43.22(IP Address of Internal NIC of Pix
firewall)
so if my Email server wants to send or receive emails it uses Pix firewall
as default gateway, its all working fine
Problems starts here when my inside users wants to use internet through
Microsoft ISA proxy server
My all clients are Secure Net type of clients, which means they will use
Microsoft ISA server as a default gateway or default router in the same
manner as my Email server is using Pix firewall.
How can I create two default gateways with different forwarding IP
addresses? In the manner that if the source IP is email server then use Pix
as default gateway but if the request comes from VLAN 102 clients then use
Microsoft IS Proxy server IP address as default gateway?
I will really appreciate all the responses.
Saleem
