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 :
