Hi,

I'm just wondering if someone already deployed something like this...

If you can't see the image, this is what I want to deploy

2 ISPs
2 ISA Servers EE
NLB in the LAN

Now, I want this, (of course) for redundancy purposes. is this possible?
I know I can make this work better if I buy a Cisco 1811 router but we can't afford it right now.

Thanks,
Daniel.

That will work for outbound access, but not for inbound access.

HTH,
Tom

For inbound, can you create Publishing rules on both servers and then publish DNS info for both rules. If one server went down Websites should have 50% success rate but email would still work if multiple MX records are published.

This is the same scenario that I am planning because our internal connection is critical but the websites we host are not.
