Why shall it be possible to access the net from the webserver? Is it not sufficient if the webserver respond to HTTP request from the net? Or does even that not work? Then you have a wrong setup with your firewall/router.



The webserver responds to http request with no problem.


Check the output of "route", check the firewalling/port forwarding rules on the firewall/router, be sure the NIC, the cable and the switch port are ok (no errors in the output of ifconfig).



Output from route:

I don't have access to the router. It's owned by the ISP and we don't know the password(It wasn't my idea), so
I am at their mercy for now.


Thanks,
