Yes, you are right.
? No, I am not right. 202.134.0.155 is an external DNS server and not the router's WAN interface IP address.
10.234.16.99 is IP number of ADSL router ( = default gateway ) in our LAN 202.134.0.155 and 202.134.2.5 are DNS servers of our ISP

Yes . . .
? No, 202.134.0.155 is an external DNS server and not the IP address of the router's interface.

You already answered a yes.
? No, I do not know what is the IP address of the router's external interface.

Yes, to the number of the ISP ( 202.134.2.5 ). No, to other numbers ( 203.130.196.6, and other numbers ). Also, a big no to other names.
I think that since you can ping your external DNS servers, your router is routing packets LAN<>WAN.

It's already there ! : resolv.conf : search telkom.net nameserver 10.234.16.10 nameserver 202.134.0.155 nameserver 202.134.2.5
Try: ping -c 1 202.134.0.12 ping -c 1 66.94.234.13
Try using only one of these DNSs at a time, then: ping -c 1 telkom.net.id ping -c 1 yahoo.com
traceroute 202.134.0.12 traceroute 66.94.234.13 traceroute telkom.net.id traceroute yahoo.com
( note : 10.234.16.10 is my internal DNS server )
Whereas the Draytek router can DNS, using an internal DNS server inside the LAN wmay slow down (1st time) DNS queries and increase LAN traffic.
# fx > Do you have access to 10.234.16.99?
Oh, I see below that it is a hardware box.
Of course, see above. I can also connect to it.
http://10/234.16.99 ?
Thank you, anyway. But, I still can't see the world via my RHL90 ( Btw, my router is Draytek Vigor 2500, is it somehow incompatible with Linux ? )
( Why do you ask this, does it work with other operating systems and not this RedHat workstation ? )
http://www.draytek.co.uk/products/vigor2500.html
(btw, No. It doesn't know or care what o/s is in use.)
Is DNS enabled on the Draytek router?
Is its web setup interface accessed via http://10.234.16.99:80 or similar?
HTH, Chuck
