General Motors TEAM Center NAT IPSEC

  • Hello, I am not sure if this post should be here or in IPSEC. I am setting up an IPSEC to General Motors for their Teamcenter application. Phase 1 negotiation works fine but Phase 2 has a responder lifetime error. I just found out that GM rejects any private IP our network is a 10 dot. GM support said I needed to NAT our internal 10dot to a public IP but I am not sure how to accomplish this and get it to work through the IPSEC tunnel.

    Any thoughts would be much appreciated.

    Thank You,

    Use a pfSense 2.1-RC snapshot. On phase 2, there is an extra box to specify the NAT subnet, and you can use your public IP or some other IP address there so they won't see your 10.x address.

    That does not/cannot work on any version before 2.1.
