I have ISA 06 with 1 external connection. I want to add another DSL connection to this box so I can have my Email going out 1 connection, and all other traffic out the other. How would I do this?

Hi there,

ISA doesnt support multipul gateways so you wont be able to do this exactly. There are workarounds however such as using a dual wan router is cisco 1812 that would allow you to run network load balancing (NLB) on 2 lines.

This is also a benifit as you could use both lines all the time for better overall bandwith leaving the network. As far as incoming goes. You would have 2 conenctions (Obviously..) but could setup 2 MX records for your different IP's in which case if one provider connection was to fail you would have your 2nd to receive.

Regards
Steve

I'll be installing another ISA box today for the other connection. Already have license and I can come up with the hardware.
