Why Can't IPsec and NAT Just Get Along?
PAGE 7 OF 7
If I knew, for example, that the NAPT device in translating IPsec would always come from an IP address on the 192.168.1.0 subnet, I would configure the IPsec gateway with one shared secret for the entire subnet. I would then have to configure each IPsec client behind that NAPT device with the same shared secret. As a result, this is really no different from how you go about typical IPsec remote access.
