I just installed RHL90, as workstation, and connected to our internal LAN.
Now, I tried to connect to the net via our ADSL. But failed, via Mozilla
browser, sendmail, or any other. The ADSL's IP number as default gateway was
already put into the routing table.
I can ping to the external IP number of my ISP ( i.e. 202.134.0.155 ), but
not to any external IP number ( e.g. 18.7.22.69 ). When I ping-ed to
external FQDN, it always said something like "...unknown host...".
Have I done something wrong during the installation? Where should I check
first?
Could somebody please help me?
My data is as follows :

P.S.
Sorry for the use of bandwidth
Hi, Frans:
10.234.16.101 fxrhl90 workstation's LAN interface
10.234.16.99 ? gateway's LAN interface
202.134.0.155 nsjkt1.telkom.net.id gateway's WAN interface ?
202.134.2.5 ns2.telkom.net.id a DNS server
I assume that the host's (gateway, that has the DSL modem attached?)
interfaces are
10.234.16.99 on the LAN and
202.134.0.155 on its ppp# interface and
that it is routing 10.234.16.0<>0.0.0.0
using a netmask of 255.x.x.0 or similar.
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?
HTH, Chuck
