I have a PIX 515E running 7.1(1) and need to establish a VPN with a PIX 501 using dynamic addressing. I can make it work using static on both ends but configuring the 515 to accept a dynamic (from 501) VPN does not work. The solutions I have found refer to using wildcard address for the key, but the 7.1 software does not handle this the same way. Using the ASDM to configure a dynamic tunnel does not work either. The IKE portion connects but IPSEC will not. Is it still possible with v 7.1?
