I have a strong hunch: After enabling IP Pool NAT, you must ARP the addresses used in your IP pool to your internal interface. For example, I'm running FW1 on NT, so I have about 25 entries in my local.arp file - a few for inbound static NATs, and the rest for the addresses used in my IP NAT pool, using the MAC address of the internal interface of the firewall. I bet that'll do the trick. If not, post again. Good luck! Dan Hitchcock CCNA, MCSE Network Engineer Xylo, Inc.

Most of the reasons deal with routing. For example, lets say your company has multiple Internet connections, in multiple locations, with a shared internal WAN between the locations. If a VPN user came into the network via location1's firewall, and you did NOT do an internal NAT pool, when they tried to access resources in location 2's network, the return packets would go out through location 2's firewall. Since that firewall wouldn't have known about the traffic, it would then be dropped, and hence the VPN would not fully work. Whew...Did that make any sense? If not, let me know and I'll clarify, but the basic idea is that you assign your VPN users a 10-dot (or whatever) tunnel address so that your route back can take a specific route and NOT a default route.... Hope this helps. Jason [email protected] wrote: > > Can someone please point me to a resource which explains exactly what IP > Pools are needed for.
