Block all traffic on Guest network except certain ports

[Ka Hooli]

Hi,

I am running an internet activity for my scout group this weekend that involves IRC and TeamSpeak.

I've configured my spare RT-AC66U router for use with a E3276s USB wireless modem, and its working well.

I've set up a guest network (with no intranet access) for the client machines to use, but I'd like to block all ports on the guest network except the ones required. From what I gather, the ports required for IRC are 6660-6669, 6697 & 113 and for TeamSpeak are 9987, 10011 & 30033.

By doing this, the youth members are less likely to get into things online that they aren't mean to get into, but I can still have full access on the normal network.

I gather I'll have to configure this with scripts, just trying to work out how. Any assistance would be appreciated.

Of course, just after I posted the message above, I find this post from about 5 months ago: http://www.smallnetbuilder.com/forums/showpost.php?p=92668&postcount=2

Now to adjust it for my needs.
