Can ISA 2006 host 2010 OWA as well as Outlook Anywhere

We currently have a 2006 ISA listening for OWA requests, with RSA Securid tag auth, to our internal Exchange 2010 OWA.
We want to start using Outlook Anywhere - will the ISA happily publish and manage rules for OA as well as OWA/Securid ?

Do we use the same external DNS name as OWA for the OA ?

Can we use the same SSL certificate for both products ?

Thanks

Thanks, Simon. Am I correct in thinking we'll have to use a different DNS CName for the listener ?
I've tried making the OA publishing rule, with a new listener on SSL, but I get an error about the existing listener being on the same port as my new one ?

Hi DoveSupport,

You only need to configure one listener,
The differnece is you will need to disable form based authentication on the OWA virtual directory and have it done on the ISA server.
Please follow steps on this link Publishing Exchange Server 2007 with ISA Server 2006. Steps are for Exchange 2007 but also apply to Exchange 2010
Also don't forget to install RPC over HTTP on the Client Access server.

Nyeama, the listener we have on the ISA uses RSA Securid auth, to get users to verify themselves. We can't use this listener for OA - we'll not have happy people who need to use their RSA tags every time they link to OA . . .
Therefore we need a new listener to use AD auth . . . but how do I configure it ?

Thanks guys, makes sense. Am I correct in my thinking below :- ?

Current setup -

Public IP - Firewall - ISA External IP - ISA - ISA Internal IP - Firewall/NAT - Exchange CAS OWA

New Setup -

Public IP - Firewall - ISA External IP - ISA - ISA Internal IP - Firewall/NAT - Exchange CAS OWA

Public IP 2 - Firewall - ISA Ext IP 2 - ISA + new listener - ISA Int IP 2 - Firewall/NAT - Exchange CAS OA

???

That's correct DoveSupport.
