Dear All, I have a ADSL broadband connection of BSNL. The ADSL modem is connected to our Internet Server (Fedora box) to one of the NIC card(eth1), the other NIC card (eth0) is connected to our LAN switch. This Fedora box acts as the gateway machine to the Internet for our LAN.
The Problem: ------------ The LAN users were not getting the Internet. I saw the PPP link was up and running on the Server and also the Modem link was ok., but I couldn't ping to their (ISP's) end. (Destination port unreachable message was coming). I called the ISP and after a while, the LAN users were able to get the Internet but during the same time, I was not able to ping to their gateway and also to their DNS IP from my Internet Server. Then when i restarted my iptables script file, i was able to ping ISP's gateway and their DNS IP too. I just want to know, when my LAN users were getting the Internet, Why I couldn't get the reply from either their (ISP's) gateway / their DNS IP. Hope someone might be able to explain me what the problem could be. Thanks in Advance, Regards, George -- http://mm.glug-bom.org/mailman/listinfo/linuxers
