Actually, the branch is an old Pix.

We also have an environment using a Juniper SRX so I'm not sure this is a good fit.  

Thanks

All to date have used static IP addressing on both sides so using the tunnel-group a.b.c.d type l2l has been very simple.  We now have a branch with PPPOE DSL and dynamic addressing.  Could someone provide an example of the ASA side how to accept a VPN site to site session from a remote device using a dynamic IP.
