Hi everyone!

 

How do I find the list of public Ip address that are and were connected to my Cisco Router 4321 on the port 85 and 6036?

 

Much thanks.

#show ip sockets - is the current, but if you looking more reports you need to consider enable Netflow or NBAR to get the visibility.

 

Routers should have IOS that supports NetFlow. When enabled, NetFlow gets traffic samples on router interfaces and forwards it to applications that gathers and displays these information. NBAR is quite similar in nature. This are great tools that provides high level monitoring but would require additional resources to implement.
