Expected results: Additional info:
Can you give me the firewall configuration? I'd need to know if you have access to the nameserver(s) and/or proxy, when the firewall is enabled.
I HAVE TO SAY FIRST THAT IT WORKS FINE AND FAST RIGHT NOW; I DON'T KNOW WHAT HAPPENED; I HAVEN'T TOUCHED ANY FIREWALL CONFIGS ON NEITHER PC OR MODEM -EXCEPT ENABLE SOME HIGH PORTS FOR PEER2PEER ACCESS ON THE MODEM. About your question: No proxy is needed or used, 2 DNS servers have been entered. There is a firewall on the RTA100 Dynalink ADSL modem preventing DOS attacks, appart from that, everything else is "default" (on both modem and PC). One thing I should try is disable the "use DNS" (and remove the addresses which are the same as the Fedora box's) on the modem, as there might be a duplication of requests; I DID THAT JUST THEN AND IT COULDN'T RESOLVE; SO OBVIOUSLY IT RESOLVES THROUGH THE MODEM DNS CONFIGURATION. I ENABLED DNS ON THE MODEM AGAIN AND IT WORKS FINE AND FAST AGAIN. It looks like there is nothing wrong anymore.
So I close it as not a bug.
