I'm having an issue with getting traffic to pass through a encrypted vpn tunnel when a server has been configured for NAT for external access. I'm using a Cisco 861w running version 12.4(22r).
I understand that I need to configure the NAT a different way but i'm not exactly sure how using Cisco Configuration Professional 2.6 (not very good at command line).
I configured the NAT for external access under the ACL -> NAT section. From what I understand I need to create a dynamic NAT and using a routemap? When I try to create a dynamic NAT it only gives me the option for adding a new or existing ACL to it.
I was hoping for some guidance on achieving this with CCP.
Here is the config for reference:
