thanx krishan
The lan side interface is definitly up for we are using it on thelocal
lan..
ifconfig on the first machine (router) gives all the ip's (192.168.3.65 and
203.122.21.204) for which the network card has been configured and there
is actually just one NIC card.
I am also attaching the ifconfig output to this mail.
As far as pinging is concerned i am able to ping from either way .. no
problems.. However pinging some external ip from the second computer
gives the following
[user@testbed user]$ ping 203.122.21.193
PING 203.122.21.193 (203.122.21.193) from 192.168.3.39 : 56(84) bytes of
data.
