Hi all,
I have a following network scenario where Debian PC #1 needs reachability to 30.0.0.0/30 network and vice-versa:

DEBIAN#1(eth0:10.0.0.50/24)------(eth1:10.0.0.51/24)DEBIAN#2(eth1:20.0.0.1/24)------(Fa0/0:20.0.0.2/24)ROUTER#1(Fa0/1:30.0.0.1/30)----------(Fa0/1:30.0.0.2/30)ROUTER#2

I was planning to use DEBIAN#2 (I have to ) as a router and route between 10 and 30 networks but not having any luck. Can someone plz help me in solving this? Thank you!

how are you trying to route it through debian #2 more info on that would be helpful.

You have 3 networks
10.x
20.x
30.x

Debian #1 knows only about 10.x but is connected to Debian #2 which can get us closer so you would have a routing entry on Debian #1 for the network 30.x going via Debian #2

Debian #2 knows about 10.x and 20.x but not about 30.x so it too would require a routing entry to 30.x via the Router #1 (assuming of course that it doesn't have a default route via it anyway)

Debian #2 also needs routing to be turned on (check the Debian docs for the preferred method)

Router #1 knows about 20.x and 30.x but not 10.x so it will need a route back to 10.x via Debian #2

If you want Router #2 to know about the 10.x network then it too would need an entry to 10.x via Router #1

All the relevant routing is configured on the Router #1 and Router #2. On Router #1, there is static route for 10.x network pointing to Debian #2 PC and this static route is redistributed into IGP.
On Debian#1 PC, I have a static router to network 30.
route add -net 30.0.0.0 netmask 255.255.255.0 dev eth0
route add -net 20.0.0.0 netmask 255.255.255.0 dev eth0

On Debian#2, also I have a static route to 30.x network pointing out of eth1.

As, suggested in other forums, i have turned on "ipv4 forwarding" on Debian#2 (echo 1 > /proc/sys/net/ipv4/ip_forward).

My challenge is to route between 10 network and 30 network on Debian#2 PC.

Following pings are successful:

1 - From Debian#1 to Debian#2 eth1 (20.0.0.1)
2 - From Debian#2 to R1 or R3

But the ping from Debian#1 to R3 (30.0.0.1 or .2) and vice-versa is not successful even though I have a static route for 30 network on Debian #2 pointing to Router#1.

You need to point these at an IP address not a physical network.
