not able to access internet(routing)

Hi,
I am not able to access Internet from pc through server but able to access internet form server.

Not able to ping from PC to dns server(10.10.10.1)/www.google.com/ 72.14.213.105) but able to do so from server(192.168.80.1 eth1).

What is the next upstream machine - 10.10.10.1?
I suspect that should also in be the "option routers" line.
(I've been wrong before...)

Thanks for your reply and please find the requested info:

MyPC--->Router---> Server( internal ip =192.168.80.1 and external IP connected to) ---> 10.10.10.1 DNS server/router/firewall.)---> internet

- From Server I am able to browse internet.
- from MyPC to Server(internal ip) able to ping but not able to ping any external sites or DNS server.
