Port Forwading
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 changed
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?
Thanks,

Routers
A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

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.
