Let's assume, for the sake of discussion, that SNMP must always work across Firewalls and NATs. The original objection to the proposed charter was that it did not include support for "Call Home" functionality. I can see how Call Home would solve the NAT problem, at least on a sporadic basis. The managed entity could initiate an "outgoing" NAT session to the management station, and the management station could use that connection as needed. I don't see how this allows the management station to later initiate an "incoming" connection to the NAT'ed managed entity. Nor do I see how it would enable firewalls to safely pass through only the desired SNMP traffic. Clarification would be helpful. Thanks. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
