Hello everybody,
Recently our college got leased line access to internet. We have a backbone
network 192.168.10.0 with the router 192.168.10.254 as the gateway.
We want to connect our electrical dept. to the internet through this network. We already had a local network at EE Dept. 192.168.1.0.
So I connected two ethernet cards to one computer (192.168.1.72(eth1), 192.168.10.72 (eth0)), and set up the routing table as follows:
-----------------------------------------------------------------------
[EMAIL PROTECTED] smal]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.10.254 0.0.0.0 UG 0 0 0 eth0
-----------------------------------------------------------------------
From this computer we can access the internet, and can also ping the other
computers on the local network.
On another computer (192.168.1.113) on this local network, I set up the routing table as follows:
---------------------------------------------------------------------------
prayas:~$ /sbin/route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.1.72 0.0.0.0 UG 0 0 0 eth0
---------------------------------------------------------------------------
But from this computer (192.168.1.113) I cannot ping the router and hence the internet, though I can ping both 192.168.10.72 and 192.168.1.72
Obviously, there is something wrong in the routing table. But what is wrong I don't know. Please help me out. This is the first time I am trying my hand at creating a routing table. (Simply trying to follow the NAG. Surely missed something obvious.)
By the way, how do I check whether IP Forwarding is enabled.
The second line of /proc/net/snmp in the local gateway shows:
--------------------------------------------------------
Ip: 2 64 9583 0 0 0 0 1840 7518 4532 162 0 0 0 0 0 0 0 0
--------------------------------------------------------
What do I understand from this ?
Regards, Santanu
