ASA duplicating rules to Global when applying to Outside Interface

Topologist

Hello All

Cisco ASA 5545

ASA Version: 9.8(2)28

ASDM Version: 7.9(2)152

We are having some issues with the ASA FW access rules. We had major network issues yesterday and to eliminate the factors, we added permit any/any for outside interface and global to rule out the FW issue. It turned out that the ASA FW wasn’t at fault but something else was.

However this morning when had a look, permit Any/Any rule removed the rest of the rules from outside interface. We realised that we were to add any/any rule in a certain line number. Rules are still present in the ACL Manager however not in the interface.

I started manually attaching the rules to the interface but realised that FW is also applying the similar rules to Global interface which is not desired. I have tried creating a new rule, copying a rule from another interface to outside interface but FW apply the same rule to outside and global interfaces. I tried deleting a rule from Global which also deletes from Outside Interface as well and vise versa.

Is there a way that we can move Access Rules from ACL Manager to Outside Interface?

For clarification:
The ACL manager should be used only when you want to apply an ACL to be applied to interesting traffic for something like a redirect acl for an access portal, etc.
When you want to apply ACLs to interfaces do it under Configuration->Firewall->Access Rules if using ASDM and assign accordingly to the respective interface. This will filter incoming/outgoing traffic.

Good luck & HTH!
