How to open telnet port to a device?

I’ve installed comodo firewall on my pc.
My security fire wall level is Safe Mode.
I created a rule at top Global Rules in Network Security Policies:
Action: Allow
Protocol: TCP
Direction: Out
Source Address: My pc’s IP
Destination Address: My pc’s subnet
Source Port: Any
Destination Port: 23
Then i use my pc telnet to router in same subnet, it’s not ok.
I try to use wireshark to capture packets for analyzing: the router sends packets to my pc in loop, but my pc can receive it.
Pls help me, thanks.

Can you show a screenshot of the Firewall logs? They are under Firewall → Common Tasks → View Firewall Events.
