Ports used by ACS for EAP-TLS

Unanswered Question
May 4th, 2010

Hi

I have an ACS 5.1 appliance, 5508 WLC and APs on what is effectively a DMZ. I need to use EAP-TLS with a Microsoft AD and Microsoft Certificate server which is on the inside of the firewall. What ports do I need to open beween the ACS server and the Microsoft servers ? 443 I assume but anything else ?

Thanks

I have this problem too.

From what  I can see in the ACS 5.1 user guide:

If there is a firewall between ACS and AD, certain ports need to be  opened in order to allow ACS to communicate with AD. The following are  the default ports to be opened:

Protocol
Port number

LDAP

389/udp

SMB

445/tcp

KDC

88/tcp

Global catalog

3268/tcp

KPASS

464/tcp

NTP

123/udp
