I’m working with a client who has a Cisco 891W router. I’m trying to establish a simple ACL that will permit connections only to certain ports from the WAN, simple things like 3389, 25, 110, 80, etc. I created what I thought was a correct ACL, but when applied to the Inbound WAN, it blocks all traffic, and renders the internet connection useless. I’ve attached the Running Config file in the hopes someone can take a look and correct me. ACL’s 100-109 were auto created apparently by the Cisco Configuration Professional software I was using. ACL 150 was created by me, but will not be used. ACL 155 is the one Ive created and am trying to use to block incoming connections. Please let me know if any more detail is needed. Thanks so much for the help.
Edit: Removed the actual WAN IP, and replaced with 333.333.333.x instead.
