OK, I understand what you're saying about private address range conflicts. But, we're a university, and our internal network is a routable subnet, not a reserved/private range as you seem to assume. And, we *can't* use another subnet like your second paragraph suggests, since only addresses in our subnet range are permitted to connect to our hosts (tcp wrappers, not changing this config). See, MS PPTP does exactly what we want, as does SecuRemote using IP Pools (but there's a potential problem with that). Seems like Checkpoint would have noticed what MS is doing & thought to provide the same type of capability.
I'll check the VPN Guide, thanks.

Office mode was developed to eliminate problems with SR clients whose IP address is in the same numbering scheme as your private network and to overcome routing issues once SR client was connected.
So based upon that you do not want to use your External addresses for Office Mode. Say your internal network is 192.168.1.0/24 you can make your office mode 192.168.200.0/24. What you need to make sure is that you route this network to the firewall.
As you mentioned above in the SmartDashboard you need to either use DHCP or configure a network object for Office mode. If you want to use a range of addresses you can do this by using the IPASSIGNMENT.CONF file where you can specify a range of addresses to assgin to a group of users. See page 153 of the R55 VPN Guide for instructions.

I think that you've hit on my problem -- I NEED the IP addresses to be part of my "encryption domain". I don't use the VPN terminology often enough to be really comfortable that I'm right, but I need the IP addresses assigned to my remote access clients to be part of my internal network, hence part of the "encryption domain" (if I've got the terminology right). This works for SecuRemote & IP Pools (although there's problems with how Checkpoint handles this, I'm told via this mail list), and also how Microsoft PPTP works for us. I can't use a separate network.
So, if anyone has an answer, I'd appreciate it.
IMHO, it seems rather short-sighted of Checkpoint not to make this type of functionality work for its customers.

I use Office Mode for my SecureClients, and do not use DHCP. I created a new network (say 192.168.1.0/24) and that is what I selected for the IP range. You can use any IP addresses you want, just make sure they are NOT part of your encrypted domain. Private IP address work perfect. Then you can assign DNS and/or WINS information (I did my internal DNS servers) and the SecureClient's will use this to resolve addresses. Works fine for us with no problems!

I saw some posts on this, and I have this question: Is there a way to allocate a subset of our internal class C subnet for Office mode client use? I.e., we have a class C subnet x.y.z.0 and we want to use say, x.y.z.101 through 110 for the Office mode clients. We just tried this with our reseller and the FW screen for this wanted to either allocate from a DHCP server (we don't have one) or a Network or Group. Not an IP Pool like we're using with SecuRemote for the time being. There's problems reported with this SR & IP Pools, so I was trying the SecureClient with Office Mode to see if it would work. The reseller was surprised we couldn't specify an IP Pool type of IP range for our Office Mode clients. Even called the Checkpoint tech rep for comment. <sigh> No help there, either.
It would be so cool if Checkpoint could do the same thing as Microsoft PPTP (only more securely), which I thought Office Mode was supposed to do, and SR with IP Pools does with caveats (except for joining the MS domain). We need the IPs to be part of our subnet range, because the Solaris hosts are wrapped to only allow connections from within our IP range... we shouldn't have to change all our Sun hosts configs just to accomodate a VPN remote access product. Might just have to keep letting people use PPTP.
CP version is R55 on a Sun Solaris system, with VPN Accelerator card II (hardly used). Thanks for any help.
