871 Firewall Help

jksnook — Mon, 11 Mar 2019 11:23:32 GMT

I am attempting to allow Microsoft communicator access from my remote 871's to our corporate office. Each 871 uses an EasyVPN configuration to access resources at our corporate office.

Communication server runs on TCP 5060 and I CAN telnet to the IP:port from the remote 871. Any idea's why the 871 is blocking the traffic?

Here are the access lists applied:

In your configuration there seems no ACL entry that will be blocking the traffic. Run debugs and check which ACL (if any) is blocking the traffic. Also are you sure that the traffic is reaching the routers and not getting dropped or blocked in between or midway.
