After moving labs.buyscripts.in to new server, one of the ubuntu PC can’t connect to it.

Ping and treaceroute fails.

I checked route

root@pc15:~# route -n

Second line

192.0.0.0       0.0.0.0         255.0.0.0       U     1      0        0 eth1

This caused access to 192.69.210.196 fail. It route traffic to LAN. For LAN, only 192.168.x.x needed.

To fix this, i added route to 192.69.0.0

route add -net 192.69.0.0 netmask 255.255.0.0 gw 192.168.0.1 dev eth1

Added the command to /etc/rc.local, so it run on boot.
