Check Point Gaia: How Do I Add/Delete A Static Route In CLI

Occasionally, when I cant get into the WebUI, for whatever reason, I'll SSH in and do what I need to do.  In many cases, its adding a static route in.  Here is how to do it in Gaia:
set static-route 10.15.15.0/24 nexthop gateway address 10.15.10.1 on

Here is how you take it out if you dont need it:
set static-route 10.15.15.0/24 nexthop gateway address 10.15.10.1 off
