Re: IP Nating problem
Did you check the client side proxy settings well.
May be the client is still using the old ISP setup for the proxy.

SolutionOpen Firefox and select the "tools->Options->Advanced->Network->Settings" and ensure that you are set-up to directly access the Internet.
From the shell prompt enter: "dig www.ibm.com" or some site you regularly use, to ensure that DNS is working. Next run: "wget www.ibm.com" to ensure you get a valid response (lot's of text) from the site.
Assuming this works then the only problems remaining are routing, nameserver and IP-Addressing problems, all of which should be discussed with your ISP.

Re: IP Nating problem
The following commands may solve your problem but they will loosen up the security in your firewall regarding client access to the internet. These are just for testing purposes. You should improve these rules using by specifying the authorized clients/destinations for your network.
iptables -t nat -I PREROUTING -p tcp -dport 80 -j ACCEPT
iptables -I FORWARD -p tcp --dport 80 -j ACCEPT
iptables -I FORWARD -p tcp --sport 80 -m state --state ESTABLISHED,RELATED -j ACCEPT
Try it and let us know how it goes.
To remove those rules from your firewall just retype them replacing the -I with -D.
