Iptables and Squid preventing internet on router not clients

I was able to get iptables and squid working and everything was working peachy. Then I recompiled the kernel with some options on for QOS (Mark and Length etc.....) and now the problem is that I can get on the internet for all my computers but with the router it doesnt do anything. When I turn off iptables then the internet on the router works. Very interesting problem.......

After looking into it further it seems that it doesnt like

iptables -P INPUT DROP

Default policy to drop input on filter....

Anyone else experience it? When I set this all the traffic on my router box goes dead. I cant ping anything or browse to anything but all my client boxes are working fine......

Assuming that there are no other rules in the input chain and your clients get to the internet through NAT, then everythinks works as it should.

The problem is that if the router which doubles as mail server, web server, etc..... cant reach the internet it cant do anything also.
