IPCop till today does not have a GUI to add static routes.

The manual method. You will have to do this every time IPCop is rebooted.

root@proxy73:~ # route add -net 10.0.0.0 gw 10.38.24.1 netmask 255.0.0.0

Now let’s make the route persistent across reboots. There are 2 files for this. Use either one depending on your needs.

You can add the route command at the end of the /etc/rc.d/rc.local file. The route will be added every time IPCop is rebooted but not everytime the interface is restarted. Good for a box with minimal changes.

root@proxy73:~ # echo "route add -net 10.0.0.0 gw 10.38.24.1 netmask 255.0.0.0" >> /etc/rc.d/rc.local

The other way would be to add the route command at the end of the /etc/rc.d/rc.netaddress.up file. This will ensure that your routing table gets updated every time the interface is restarted.

root@proxy73:~ # echo "route add -net 10.0.0.0 gw 10.38.24.1 netmask 255.0.0.0" >> /etc/rc.d/rc.netaddress.up

I personally use the latter.

To view your routing table run the “route” command.

root@proxy73:~ # route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
213.27.199.80   *               255.255.255.248 U     0      0        0 eth2

To view the current routing table run “route -n

[root@klmppswdr01p ~]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.41.42.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.41.41.0 10.41.42.8 255.255.255.0 UG 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 10.41.42.1 0.0.0.0 UG 0 0 0 eth0

To add a route refer to the command below.

"route add -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8"

To delete a route refer to the command below.

"route del -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8"

The routing information above is not persistent across reboots. After a reboot, the routing information will be lost and you need to add them in again.

To make the routing information persistent, add the “route add” line as seen above into the /etc/rc.local file.

Sample /etc/rc.local file.

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
route add -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8
