Does anyone know of a good reliable packet filter software for windows? I am looking for something similar to what an ACL does in the cisco world. Which would be software that will alow me to allow or disallow any type of ethernet packet based on protocol, port #, ip address etc. If anyone has had any luck with any software that will accomplish this then it would be much appreciated to let me know.

maybe something like this:

It mainly does it at the DLL layer it seems but might be close to what you are looking for..

never used it, never really saw the reason too...

If I might ask, why do you feel you need it?
Dont you have a router to seperate your network from the internet?

well, windows server has some basic packet filtering built in..

How is your network setup? Are you using this windows box as a firewall? Are there two NIC's in this box?

no server, this is for home. Just a simple 4 port switch with router. 1 NIC

you should be able to use any semi-decent client firewall to setup a rule to block packets based on ports and destination..

i personally use (alongside my routers firewall) agnitum outpost 4 as a software firewall, but agnitum has started to become resource hungry bloatware (probably wont renew my license, their support has gone to crap too)

I'd say your best bet is to pop an openbsd or freebsd box between the router and the switch and have it filter and forward traffic and disable the firewall on the router if possible. Then you can get almost as powerful as carrier grade routers and switches :)

I would highly suggest getting a Linksys (Cisco) or equivalent router and using the built in security features in there.
