Yes, it's possible to configure a group of subnets that are to be included
in the "encryption domain" on the Cisco concentrator.  When you set up the
LAN-to-LAN settings on the Cisco box down towards the bottom are the
settings for the remote and local networks.  If there are multiple networks
on both sides you will need to use the "network list" option for the remote
and local settings.  To define a network list see the link below:

Hi lads,
I've been trying to configure a VPN between a Check Point NG (FP1 and
FP3) to Cisco Concentrator 3000 VPN. Finally, I was able to establish
the tunnel. I had the following problem:


   |-------[CP NG FP3]----Internet----[Cisco]----|
Net 1                                          Net 2

When I ping (as in access anything at all) from Net 2 to net 1,
everything is fine.... when you try to ping from net 1 to net 2 only
phase 1 is completed but phase 2 isn't. The message that I get in both
logs is that the Cisco is sending a "delete SA" message to the Check
Point peer.
After some research, I found out that this is due to the Cisco peer:
both encryption domains must be set exactly alike. I mean, both
Encryption domains must be configured as the same subnetwork... it is
not posible for you to have a Class B encryption domain defined for the
Check Point (in the Check Point object) and a class C encryption domain
defined in the Cisco side (for the Check Point encryption domain).

I configured the same subnet as the Check Point encryption domain in
both peers, and everything worked fine.

Now, I have the following question for you guys.... what if I have a
group defined in the Check Point side as the encryption domian?. It is
not posible to configure a group on the Cisco side... it has like a
field that you can fill with a subnet and a mask (I don't know that much
of the Cisco concentrator, actually, I don't know anything at all!,
that's why I came to you....). Is it posible to define like a group, or
a list, as an encryption domain?.

What should/can I do?.

Cheers, nd thanks,

LB
