A sample config to enable OCS Edge via a Cisco ASA 5520!
(Moved from my Live Spaces blog – may need update)
We just recently installed a Cisco ASA 5520 as an external firewall, along with some internal network redesigns.
Concurrently, we've been working on an OCS Enterprise Voice deployment, with the Edge server role forming part of our plans for conferencing and meetings.
I had a couple of minor hiccups with the config, and info was fairly sparse, so I thought I'd pop the specific rules up.
Cisco ASA 5520 or similar; already configured and operational with an outside interface
At least 1 DMZ interface with private IP address
Single OCS Consolidated Edge role server, with A/V edge role set as being via NAT
Single external NIC on Edge server, with multiple IPs in same VLAN as ASA 5520 for the various roles
Federation to OCS 2007 (not R2) may be required, needing an inbound rule for A/V
Naturally I make no warranty as to the suitability of this ...
