Ports Opened

ray_stone — Mon, 11 Mar 2019 13:02:20 GMT

Hi, We are using Cisco ASA 5505 in Production and I opened few ports for Servers to provide access from outside. I have added 80, 443, 8800, 9500 but when I try to telnet Server IP (telnet 196.44.242.12 80) then it responds and when I try to use telnet 196.44.242.12 8800 then it responds failure. Please advice.

Hi Richard,

It is possible

1- App is no listening on port 8800, can you

confirm by doing telnet using local ip on that port or do c:\netstat on the server to see listening ports.

2- Double check your access-list perimiting port tcp 8800 or ensure 8800 is in your tcp object-group if using one for your acl.

3- Do you see anything in the logs indicating no connections or denys on that port .

Or try the packet-tracer command

packet-tracer input outside tcp 4.4.4.4 1024 196.44.242.12 8800 detailed
