Hi:
My network is like this:
A(IP:192.168.0.2) B(IP: 192.168.0.1)(IP:192.168.1.2)
C(IP:192.168.1.1)
(netmask:255.255.255.0) 255.255.255.0 255.255.255.0
255.255.255.0
(gw: 192.168.0.1) gw : 192.168.1.1
B is a machine with 2 network cards .
At first I enable the /proc/sys/net/ipv4/ip_forward and set the default gw
192.168.1.1.
Now, A ping B is ok and B ping C is ok. But when A ping C the network is
unreachable.
I don't know why. Please help me.
Best wishes.
Thank you.

I'm not sure what you mean because of wrapping.
You mean this?
A(IP: 192.168.0.2)
(NM: 255.255.255.0)
(GW: 192.168.0.1)
B(IP: 192.168.0.1) (IP: 192.168.1.2)
(NM: 255.255.255.0) (NM: 255.255.255.0)
C(IP: 192.168.1.1)
(NM: 255.255.255.0)
(GW: 192.168.1.1)
You should change the GW of C into 192.168.1.2.
C does not know the route to 192.168.0.2; B does.
