Hi,
What are you rules like?
Here is what it looks like from reading this post:
Your default rules are deny or reject as opposed to accept.
You may be missing/misconfig the line to allow established and related. That 
would explain why ping works and traceroute. They are icmp messages, not 
established connections. 

can you post either your rules or else the output of
'iptables -L' (as Benjamin included).
