Reply To: No option to configure gateway for VoIP NIC

Some Linux distributions allow you to configure routing information along with the NIC (in the same NIC configuration file); however, this is misleading – in fact, newer Linux distros no longer allow this practice. Routing information has nothing to do with the NIC. Routing information (eg: default gateway / subnet gateway) is added to the routing table not the NIC.

If you would like to add a route to the routing table from a terminal window then enter a command like:


route add -net 10.10.0.0 netmask 255.255.255.0 gw 10.10.0.1


If you would like this route to persist between reboots you would have to enter this information into a config file/script. If you are using the Commercial Unlimited edition of HAAst then you can add the above line to the pre-start event handler /usr/local/haast/events/asterisk.start.pre This event handler will run before the vNIC is brought up so the route will be present when needed. If you like you can also delete this route by adding a line to the the post-stop event handler /usr/local/haast/events/asterisk.stop.post

If you are not using the Commercial Unlimited Edition of HAAst, then you will need to find the most suitable place for these routing rules (which varies considerably between Linux distributions). In your case I suspect you are using a RedHat flavour of Linux, so you could create a file called /etc/sysconfig/network-scripts/route-eth0 with:


default 192.168.0.1 dev eth0
10.10.0.0/24 via 10.10.0.1 dev eth0
172.16.1.0/24 via 192.168.0.1 dev eth0


but you should check the guides for your Linux distro to confirm the best place to place ‘persistent routes’. If you are looking for routes to be added/deleted based on HAAst events then you should use the HAAst event handler instead.
