Save the bandwidth!

[dave]

Sharingwith students, theres only so much "don't use filesharing coz it kills the bandwidth for everyone" talk you can do before its time to call it a day.

I'd like to setup my router so it will allow normal web browsing during the day and other low bandwidth applications, but prevent filesharing by blocking ports. I know I can do this on my router, but can anyone suggest a good configuration such as block all ports but allow friendly ports. The suitable ports I can think to unblock are:

Http : 80, 8000, 8080
Ftp : 21
MSN/Yahoo/Aim : ???
DNS: ??
Anything else? : ??

A good site to look at is http://www.portforward.com. I also came across this discussion which may be of use. To be honest, many of the filesharing tools can use port 80 etc.

IMHO - rather than blocking them, if your router lets you, just throttle the blighters...

Charge them extra if they want to use those ports.

List.

I should probably move this to hardware now.

Thanks for your help, rather then deny access to filesharing ports - I would prefer to only allow to access for "legitimate uses"

So what ports would be needed for legitimate uses? So far all I can think of is Web, Msn, Dns etc, anything else? Any ports needed for SMTP or POP? etc...
