Setting up openSUSE as router is not too difficult. The setup process only needed a few step to completed, as shown in the following wizard :
Configuration :
eth0 IP Address : 197.187.87.0/28 eth1 IP Address : 165.155.121.0/24 Gateway : 197.187.87.1 DNS 1 : 215.155.200.45 DNS 2 : 215.155.200.46
- Activating router function
echo 1>/proc/sys/net/ipv4/ipforward
- Create a routing with network as a target
route add -net 168.155.121.0/24 gw 165.155.121.1
- Create a routing table
iptables -t nat -A POSTROUTING -s 165.155.121.0/24 -j MASQUERADE
- Saving IPTables setting
iptables-save > /etc/sysconfig/iptables-net
- Make sure IPTables will be started while booting
vi /etc/init.d/network
- Add the options :
iptables-restore < /etc/sysconfig/iptables-net
- Save the configuration
- Check the router function by running ping command from host client into internet address
Reference (Indonesian) :
Random Post
eth0 = LAN?
eth1 = Outside?
or is it the other way around
Thanks saved me hours, I keep my servers in the garage on their own subnet , now I can access them from the comfort of my living room.
