Hi everyone!
I'm trying to connect two networks togheter with a linux server(redhat7.2).
To do this i did the following on the gateway.
1. installed 2 nics(3com card), linux founds them(dmesg | grep eth)

2. edited /etc/sysconfig/network

NETWORKING=yes
FORWARD_IPV4=yes
HOSTNAME=gw.test.domain.se
DOMAINNÄME=test.domain.se
GATEWAY=192.168.110.1

3.echo 1 > /proc/sys/net/ipv4/ip_forward

4. edited /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
IPADDR=192.168.110.96
NETMASK=255.255.255.0
NETWORK=192.168.110.0
BROADCAST=192.168.110.255
ONBOOT=yes

5. edited
DEVICE=eth1
IPADDR=192.168.111.1
NETMASK=255.255.255.0
NETWORK=192.168.111.0
BROADCAST=192.168.111.255
ONBOOT=yes

6.restared the interfaces
ifdown eth0
ifup eth0
ifdown eth1
ifup eth1

To do this i did the following on the clients of the subnetted net

7. edited /etc/sysconfig/network
NETWORKING=yes
FORWARD_IPV4=yes
HOSTNAME=gw.test.domainn.se
DOMAINNÄME=test.domainn.se
GATEWAY=192.168.111.1
GATEWAYDEV=eth0


8.echo 1 > /proc/sys/net/ipv4/ip_forward

9 edited /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
IPADDR=192.168.111.2
NETMASK=255.255.255.0
NETWORK=192.168.1110
BROADCAST=192.168.111255
ONBOOT=yes


10.startat om interfacet med
ifdown eth0
ifup eth0

And this is were i am now.
I can ping the internet and the 192.168.111 net

I cannot ping 192.168.111.2 from 192.168.110.1

I cannot ping 192.168.110.1 from 192.168.111.2
but I can ping all configured host on the 192.168.111.0 net
from the 192.168.111.0 net

In step 9, you appear to have ommited periods on the network and broadcast errors. There is a vast difference between 1110 and 111.0 in the ip scheme of things. 1110 will map to 4.90, which does not fit in the netmask.

In any case, you will need to add a routing statement on your default gateway machine in your 192.168.110.0 network. This will look like:

route add -net 192.168.111.0 gw 192.168.110.96

Note that this is not set up on 192.168.110.96, if your default gateway to the internet is for example 192.168.110.1, then that device needs to have the 'route add...' statement set up.

Alternatively if there are only a few devices in the 192.168.110.0 network that need to talk to devices in the 192.168.111.0 network those could be set up with the 'route add...' statement. In this case I am not sure how to set up a windows9x machine. For these machines you will need to have the route set up on their default gateway.

ahhh. of course.
This solved my problem. Thanks!!
