I have a network as follows:

PIX Firewall 525 uses three network interface Ethernet1, Ethernet2, Ethernet3.

E1 (10.0.0.1, Inside) connected to LAN

E2 (117.16.126.35, Outside) connected to the modem (117.16.126.33) ISP1 (This address by the ISP level)

E3 (192.168.1.2, Outside2) connected to the modem (192.168.1.1) ISP2 Divided into two network subnets:

Network1: 10.0.0.0 - 255,255,255,126 to be NAT addresses 117.16.126.35 and 117.16.126.33 use a default gateway (ISP1)

 Network2: 10.0.0.128 - 255,255,255,254 to be NAT address 192.168.1.2 and use the default gateway is 192.168.1.1 (ISP2)

The problem is I do not configure the default gateway 2 for 2 outside and outside2 interface. I configured as follows:

Route outside 0.0.0.0 0.0.0.0 117.16.126.33 "Success"

Route Outside2 0.0.0.0 0.0.0.0 192.168.1.1 "not successful"

Looking forward for help how to configure two default gateways to be 2 ISP

Thanks. We'll let you know when a new response is added.

first you configure your network2 modem into full bridge mode and then you will get a public ip addres on PIX.

You can use two default gateway but with different Ad value. If one goes down the other will be used.
