Agree...

It would be very helpful if the OP would simply state their network
configuration when connected.  That is, the correct IP address as well as
the subnet mask.  As in the output of "ifconfig".

It doesn't help to obfuscate ones network configuration/settings when asking
for help on networking issues.

Posting something like...

eth1      Link encap:Ethernet  HWaddr 00:04:23:46:CE:22
          inet addr:203.70.27.121  Bcast:203.70.27.127  Mask:255.255.255.248
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:5321094 errors:0 dropped:0 overruns:0 frame:0
          TX packets:5184333 errors:0 dropped:0 overruns:0 carrier:0

Isn't going to make you open to attack.
