double ISP link & publishing ressources - 19.Oct.2007 4:41:33 AM

Hello Everybody,

Here's a descriptive of my actual setup:

ISA 2004 SP3, 4 NICs (1 LAN, 2 DMZ, 3 ISP-A, 4 ISP-B)

LAN & DMZ are private IP ranges.

ISP-A link = 1 public IP address (/30 subnet)
ISP-B link = 12 public IP addresses (/28 subnet)
a default gateway is set on each external NIC
traffic on ISP-a works ok :)
I've bound the IPs from /28 network on the NIC4 (ISP-B), i also added
Original setup was through the wizard 3legs setup as ISP-B has been added later. I've never used ISA in a 4 legs (2 external) config.

problems:
1- I don't see anything from NIC4 (ISP-B) for setting any NAT or any rules. I'd like to "map" some external IP addresses from the bunch I have on NIC4 (ISP-B) to several services: publish DNS, WWW, SFTP and few other things.

2- I'd like to eventually load balance outgoing http traffic from users, but it's a nice to have.

Questions:

1 - Is my network basic Setup correct ?
2 - How to see and use the available IPs from NIC4 (ISP-B) in my rules ?
3 - Do I need to reconfigure the full ISA ?

Any advice would be great.

thanks in advance

Regards

Peter

Hi,

ISA Server Does not support multiple gateways ( ISPs )
