Hi there, I have a couple of questions:

1. To what interfaces and what direction are the listed ACLs applied?

2. Have you tried using the packet-tracer feature to determine what is blocking the traffic?

Thank you for rating helpful posts!

Dear Neno Spasov,

1) I want to external (WAN1) to internal (inside)

2) I tried packet-tracer, when remove "access-list WAN1_to_inside extended permit ip any any" no packet can access ERPServer.

Can you post the output from the packet-tracer result?

According to what is posted the access list has two inactive statements and one active statement (which is the permit any any). If you remove the permit any any then there is no statement permitting your traffic from outside to access the server.

access-list WAN1_to_inside extended permit object 12322 any object ERPServer inactive
access-list WAN1_to_inside extended permit object 12443 any object ERPServer inactive
access-list WAN1_to_inside extended permit ip any any
