Glen, IPSECME WG <http://www.ietf.org/html.charters/ipsecme-charter.html> at IETF is actually working on the exact issue that you have described (unable to deep inspect ESP-NULL packets). You can look at draft-ietf-ipsecme-traffic-visibility-02<http://tools.ietf.org/html/draft-ietf-ipsecme-traffic-visibility-02>for more details.

Hi,
It is well known in the community that AH is NAT unfriendly while ESP cannot be filtered, and most firewalls would not let such packets pass. I am NOT

interested in encrypting the data, but i do want origination authentication (Integrity Protection). Do folks in such cases use AH or ESP-NULL,

that both have some issues?
Thanks, Glen
