Why can't my IPsec VPN clients connect from behind NAT?

Related QuestionsWhat is the difference between an IPSec VPN and an Application Level VPN?
Work Anywhere - Wireless, Mobile, Satellite Internet.Although IPSec is considered the standard for network security, it is a strong solution only for site-to-site protection.

m0n0wall HandbookThere are two ways to accomplish this. Which is most suitable depends on if you are able to summarize the subnets, and how many subnets are involved. For either way, the subnets do not need to be directly connected to m0n0wall. They can be behind a router on the LAN behind m0n0wall. In that case, you'll need to set up static routes on m0n0wall's LAN interface pointing to the LAN router for each of the subnets in question. You can also summarize the subnets in static routes.
