if you read my last post, i showed you how you setup the default gateway ip address in your linux server, how about if you only want to see it, well, just send this command to show you what the default gateway is:

# route -n

the outpu might look like this: 

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
210.83.41.94    0.0.0.0         255.255.255.224 U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth0
0.0.0.0         208.86.44.97    0.0.0.0         UG    0      0        0 eth0
this command will also show you the routing table
