Port Forwading

Last Modified: 2020-05-20
Local pizza shop owner was getting attacks on router, the POS system was crashing, not printing etc.

He called Comcast and tech said router was being attacked from outside and they could not help.

 I logged into router and changedRouter Port Forward Settings the password.   I noticed that there is port forwarding turned on for ports 11761, 11762, and 11763.  See attached image for what I see.

Is it normal for port forwarding to be turned on for these ports?  Does it have anything to do with the external attacks?

Provide more description about what an attack might mean.

Tip: Talking to Comcast... about anything... like playing darts with a blindfold... someone will get hurt... target will never get hit...

Before you invest any time in this project, best you do your own analysis to determine if there really is an attack, how it's occurring, why it's occurring, etc...

Then proceed.


See attached for attack info.
