Which TCP ports does windows networking use?

I would like to set up a dump wifi AP so that PCs attached to it can't
see other PCs on the network. This AP can do port blocking.

Fix your son's laptop. Much easier.

Why not look at setting up VLAN's with a suitable router/WAP?

Seconded.

Have done, mate. That was another project.

Hopefully somebody else will answer the simple question.

Sure it was. Another project that just happens to coincide 100% with
your requirements to prevent your son's malware-infested PoS from
infecting your nice pristine desktops.

Pull the other one.

Thankfully I found it on google in less time than it took you to type
up that useless response.

TCP Port 139 looks like the one.

windoze networking using several different ports, (and a worm or virus may
use different ones to attack another PC).

Standard security paranoia is to block everything and only let thru stuff
you do want.......

2 cascaded routers may give you an easier setup.

Internet --- b/band ---- wireless router --- 2nd router

the NAT on the 2nd router will limit access from wireless, and you can use
DMZ features to let specific protocols thru.

2 alternatives / suggestions

1. ask on alt.internet.wireless where the wireless specialists are found.

2. look for an AP where each associated device cannot access other wireless
devices - this function is often used in hotspot setups to restricts
different users from accessing each other.
Not got it on my kit so cannot recommend any specific device.....

Currently I am happy with just 53 80 443 open; that does most "web"
things fine.

Yes, I am using NAT (2 cascaded NAT routers) in another installation
to achieve this; it works well. However in this case I don't have that
option because it would involve reconfiguring a lot of other stuff
which was a pig to get working.

Thank you. I believe the pricey Cisco APs (Aironet 1100 1200 etc) can
do port blocking and these tend to be used in internet cafes. These
come up on Ebay all the time. If one opens just 53 80 443 then windows
networking will not see anything else anywhere else.

Though you should probably be asking yourself why you didn't do that
in the first place, google is your friend for that sort of query.

and UDP 138 and TCP 139 and 445, to cover all bases including
printing.
