Cisco ASA Firewall settings
Posted on 2011-09-27
My environment has two separate domains, with a Cisco ASA 5520 acting as Firewall/router in between the 2 domains, and between them and the internet.
Domain A uses the "Inside" interface and has 3 domain controllers
Domain B uses the "Public" interface and has 2 domain controllers
I need to set up domain trust between the domain controllers in the 2 domains.
Right now, All domain controllers on domain A can ping all DC's on domain B.
NO domain controllers on domain B can ping any DC's on domain A.
What access rules do I need to configure on the ASA to allow DCB1 and DCB2 access to DCA1, DCA2 & DCA3, while blocking any other traffic from domain B to domain A?
I would appreciate some assistance, as right now all traffic from B to A is blocked and I cannot create the trust.
