Open Ports

[userice]

When I scan ports, I found Port 23, 79, 80 are open. What should I do to close them. Here is my configuration.
I do have a router in front of the PIX

Internet <---> 216.170.x.y (Router) 192.168.2.199 <---> 192.168.2.200 (PIX) 192.168.1.199

Most likely these ports are dynamically openned as your inside users use the web. If your network is small enough, try a port scan again after everyone has logged off, and you've issued a 'clear xlate' from the command line.

HI.

These are probably services running on the router itself.
Consult your router documentation.
