Multiple SSL Sites on ISA 2004

Hi there,

quick question. we are currently running an ISA 2004 server which has Outlook Web Access setup with a listener on port 443 for SSL. it is using a certificate from a local CA.

we recently implemented Sharepoint into our environment and i was requested to setup a portal for external users. i have set it all up and we used a signed certificate from thawte.

is it possible to have 2 listeners on ISA for SSL to Port 443 over 2 different IP's on the external NIC? or will i have to scrap both certificates and request a wildcard certificate from thawte?

i am able to make both work, only one at a time though.

Thanks,
Jonathon

Perfectly acceptable.

Add the 2nd ip address on ISA's external interface. at the OS level in the tcpip settings. (obviously make sure your external devices pass this ip through to the ISA external nic....)
open the ISA gui and edit youir OWA rule
in the interfaces (to/From) section, where you selected External,you will now see the addresses button is not greyed out. Select the specific IP address that OWA should be listened for.

Now you can perform your sharepoint rule and when you select external for the listening interface, go into addresses and select the 2nd ip address.
