I am looking to secure the access to ACS 3.3.3 on a Windows 2003 SP1 server. I am running only radius and access to an external Windows database. Currently I am looking to allow:
- tcp 2000 -> ACS replication
- udp 1645 -> RADIUS authen & author
- udp 1646 -> RADIUS accounting
- tcp 443 to port 2002 -> management
What I am trying to figure out is what I need open for the Windows external database. MSCHAP v.2 requires TCP 1723. Is that all that is needed?
Any advice would be greatly appreciated.
