PACKET FILTER PROBS WITH NAT

I was trying to use a Win2k server to replace a linux router for a small soho. Here is the skinny. I installed server, no probs, configured NAT no probs.
When the NAT wizard starts I choose "network router" So I may configure it myself. I do not use the DHCP, just the DNS proxy. It all works fine until... I set up the packet filters.
In the filters dialog box, one of the options is to filter everything but "tcp (established)" connections. I choose that option, then click the radio button that signifies "drop all packets that do not meet the requirements below" Once that filter is in place I am hosed, no clients get net access, the router does not get net access. I then get an error, that states that " the DNS proxy could not resolve request from my internal cliet".
Now, am I in the wrong about the filter. It should allow connections from the internal network, right. Just not allow new incomming connections. At least that is what I have been told. OR could it be that it only allows current established connections, no new ones. Any help is greatly appreciated.
