However what if your neighbor wants to IPSEC to the same place (say you work at the same place). If both of you are NAT'd from the same IP address trying to IPSEC to the same IP address? I don't believe things will work in this instance.why not? We use it here, works fine (with certificates for auth).
From what I've seen it depends on whether the NAT has specific support for IPSEC, and if that support includes support for multiple clients. The NAT box has to keep track of the mapping. I've seen NATs priced based on how many VPN clients they support at a time.
