New to checkpoint - stuck on a section, plz help

[snipesnab]

I have setup and configured checkpoint basically. The server that is running checkpoint has 3 network cards, each with a different IP address. When i log into checkpoint and edit the checkpoint firewall properties i navigate to the topology tab.. this is where i am having my problems. It says that all my network card ip addresses are external and the option to makev them internal is greyed out. Does anyone know why they are greyed out and how i can be able to set them up as internal.

I have setup all my networks and hosts etc.

Your help would be greatly appreciated.

I have seen this before and it was because the firewall object has been created as a host and not a gateway object. If this is the case you should be able to simply right click the object and select 'convert to gateway...' then follow the wizzrd or prompts.
Let me know if this is the case.
Thanks and good luck.
