are you seeing issues with all tcp or just web traffic? One other thing you might want to try out is to fire up tcpdump (tcpdump -i eth0 -n ) and run: traceroute -n google.com and traceroute -n -T google.com The -T there, tells traceroute to send out tcp packets. It could give you some insight on what may be causing this issue, or at least where the issue might be.
