Hi to all,
i have 2 networks.
A. 192.168.0.0 255.255.255.0
B. 192.168.1.0 255.255.255.0

and i want computers of A network contact computers of B network, and B network contact the A network.

I have make a PC with debian (or i can use redhat) and 2 net cards (192.168.0.200 & 192.168.1.200).
I have config the cards but how i can add a simple routing?
I just want connect of A net to B and from B to A.
No internet, no anything else, just share the 2 networks.

Can everyone help me how i can do this simple?
Thanks and sorry for my bad English.

turn on routing.
echo "1" > /proc/sys/net/ipv4/ip_forward

configure clients to use linux as gateway.
thats all.

Hi,
thanks for the answer.
I have do this but i think needed and some more config. You are sure that it is not needed some route commands?
thanks a lot.

If you have configured the clients to use the gateway as a default route, all you have to do is use the ip number in the other network to connect. The router does all the smart routing stuff..

If you want to use Window$ network browsing, you need to set up a WINS server on the router box.
This is part of the Samba package.
just add wins support = yes in the smb.conf file
and tell the clients to use the WINS server at the gateway address..

I have do this.
...the IPs of the router is:
eth0:
192.168.0.160
gateway 192.168.0.10 (my office gateway)

eth1 192.168.1.1

i have all add this configs but o PC (win2000) with IP: 192.168.1.12 can ping the both 2 interfaces of the router but no the PCs of the other network.
Any info about this?

You all sound out of line. He hasn't got a router
The man can't speak good english. He just wants to connect two pcs.
This is for blue ice:
Read the NFS Howto, if you can manage it. Look up www.tldp.org.
Connect your two pcs with a crossover cable, plugged into your ethernet cards in A and B.
For a start, disable all firewalls.
Configure the files hosts.allow hosts.deny and exports all to be found in /etc.
Then run as root in a terminal
ifconfig or /sbin/ifconfig, to make sure your eth0 card is running.
Then do in a terminal
/etc/rc.d/init.d/nfs start
Check with
rpcinfo -p to see that nfs and portmapper are running.
Do the same on the other computer.
Then try ping -c 10 192.168.1.0 see what you get. I spent ages getting my two connected, none of the wizards worked.
If you want examples of hosts.allow, hosts deny and exports, send me a mail and I'll beam it over.
Good Luck.

Add MASQUERADING to both interfaces..

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

(Forgot about that step, sorry)

thanks a lot
i will try today

is MASQUERADE-ing required? This is a simple routing configuration.

bueice, you can edit /etc/sysctl.conf and set

net.ipv4.ip_forward = 1

Once this is done, you can

#sysctl -p

This iwll ensure that if you ever reboot your pc, you wouldn't need to retype the

echo "1" > /proc/sys/net/ipv4/ip_forward

or put it in the rc.local file.
