pix 501 to 3030 using dynamic outside ip

[bbelz]

Is it possible to do a lan to lan vpn (ipsec) from a pix 501 using a dynamic ip address on the outside interface. To a cisco 3030 concentrator.

Yep.

This shows the config on the VPN3000:

The config on the PIX is just a standard L2L configuration, just make sure the pre-shared key on the PIX matches the Default Pre-Shared Key configured on the 3000 in the Base Group.
