Can you ping the gateway's external interface by IP address? "I can ping to the external IP number of my ISP ( i.e. 202.134.0.155 )" I assume that 202.134.0.155 is the IP address of the gateway's external interface and the answer is yes. Can you ping 202.134.2.5 or 203.130.196.6 ? (ns1.telkom.net.id or ns2.telkom.net.id) For ping'ing by FQDN you will need 202.134.2.5 (or similar) in /etc/resolv.conf (or RedHat equivilant). Do you have access to 10.234.16.99? What assumptions of mine are incorrect?
