Hi!!
I am relatively new to Linux. Any help in this regard will be highly appreciated.
I am trying to setup private testbed network using Linux 2.4.18 kernel and for that purpose, I have some machines configured with 2 NICs. Although i can ping any two directly connected machines from each other on each of their interfaces but cant go any further than that.

I have tried setting /proc/sys/net/ipv4/ip_forward as 1 but to no avail. To my adventures, I realised that i couldn't ping eth0 from eth1 interface and vice versa.

Thanks in advance.

Trying for the same.


This is one way i can think of:

1) enable ip forwarding
2) Then run iptables as follows

iptables -A FORWARD -i eth0 -o eth1
3) add the route in the routing table .


Any help appreciated.

Thanks,
Abdul.

hi,
yes enable Ip farwarding by editing


echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -A FORWARD -i eth0 -o eth1
iptables -A FORWARD -i eth1 -o eth0

Kind regards,
Farrukh.

Hi,

Enabling ipforwarding should do bcoz kernel performs routing by default.

plz assign different ip to both the interfaces and check
netconfig --device=eth0
netconfig --device=eth1

service network restart
.

But enabling ipforwarding is a must.

Thanks,
Abdul.
