Our internal network is ... erm ... complicated!

How would I manipulate the routing table within Filr to add static routes to different networks that use different internal gateways?

I had a look on the console but there appears to be a limited route command and nothing on the web gui interface that allows static routes to be added.

I tried to edit /etc/sysconfig/network/routes but it's read only as vaadmin.

Many thanks in advance,
