I have been reading a lot of questions and answers here regarding IPSec, and NAT and still a bit confused. I have a Cisco 3640 Router as my gateway, and have NAT configured, some static mappings as well as dynamic.
IOS Version: 3600 Software (C3640-JK9O3S-M), Version 12.2(13)
I am looking for how to allow IPSEC Pass through on the router with NAT? I do have some ACL's applied, and looking for either some help with the config, or a url , pointer to look at and read up on it.
I can post part of the config file if needed, just need to know what parts would be pertinent.
Thanks in advance for the help.
