Can anyone tell me what version of the 12.2 SX train has support for nat-t with ipsec/isakmp? The software tools are no help, and I haven't gotten very far with TAC. I am running 12.2(17d)SXB10, and am having trouble getting a netscreen to connect if it is behind nat. It works fine if no nat. From the isakmp debug, it looks like the MSFC recognizes NAT-T, but the 'crypto isakmp nat-transparency' command is not recognized. I need to know if my problem is release-related or an interoperability problem. Thanks
