After upgrading a 4000 appliance form R77.30 to R80.20 we had issues where any static or default routes were not added to GAIA. To add the static routes I had to issue the Expert (Red Had) commands of ip route add. CLISH shows a "Syntax Error" when trying to add to GAIA.
I worked with Check Point for several hours Saturday morning, and they suggested a fresh rebuild. Unfortunately this system is in London, so doing a remote rebuild is difficult, no LOM or Serial access.
Since this is a single firewall, if there is a power issue or this system reboots, it will not add the routes allowing access back into it from the US. Is it possible to add the routes to some of the network startup scripts until we are able to coordinate a rebuild?
