Re: [FW-1] Firewall IP address internal???



Hi ;-)),

in my opinion there is no need to change te main IP- Address of your
firewall in the GUI. I assume you have objects for your firewall, in the
first raider you have entered the IP you are talking about and in the
"interfaces" raider you have all the other interfaces (done by snmp get).

I personally prefer your setup, so that the management and the filters are
on the same subnet. However in some strange cases I have seen the filter
talking back to the management with its external IP. This was a licensing
issue. I think your Fiilters are licensed to the internal IP which is shown
in your GUI, aren't they ?

If I was you, I won't feel the need to chnage anything.

Subject: [FW-1] Firewall IP address internal???

Hi friends,

We are running two Nokia's IPSO 3.2.1-fcs1. FW-1 4.1 SP2.

Yes, we will be upgrading IPSO and FW-1 to the latest SP's soon.

My question is with regard to the way our firewalls were set up.

Our management workstation has an internal IP address. And both of our
firewalls are defined in the rulebase as objects with INTERNAL IP
addresses.

If I am using IPSec only for VPN's and never use SKIP or FWZ, is there
any
reason why I should change the objects to use external IP's???

If I do change the IP's to external, will I have any problems in using
the
internal management workstation when pushing policies to the firewalls?
I
once worked with a company that had two Sun boxes with 4.0 and they had
external addresses. Every time we pushed a policy, the connection broke.
The
firewalls were defined as objects with external addresses.

I have Dameon's Essential Check Point book and he states early on that
you
should use an Internet routable address for the firewall objects. The
book
doesn't explain why this is his suggestion. And I am wondering whether I
should go through the reconfiguration or not.

Thanks for your help in advance,

Mike Hawkins
