What is the configuration when one PIX (515) has a static address and the other PIX (506) is attached to a cable modem and has a dynamic address? Also, can there be more than one remote PIX with a dynamic address?
you have to configure a dynamic crypto-map on your 515 and a dynamic pre-shard key (address 0.0.0.0). The 506 (or more of them) have an ordinary crypto-map with peer setting etc. All 506 must use the same pre-shared key, so better use certificates. Tunnel direction is always 506 --> 515.
