We are running Cisco ASA 2220 version 8.4(3).
In previous attempts we have been unable to firewall Microsoft DCOM communications and generally any Microsoft RPC comms although the last time we attempted we were running an older model of Cisco ASA.
Is it possible to use a policy map to correctly open the pinholes for Microsoft RPC communications? If so what version of IOS is required and would anyone have a configuration example?
Has anyone had success with this?
Many thanks in advance.
