Site-to-site VPN, dynamic IP address and PAT

[adalessandro]

Hello Forum

I need to set-up a VPN connection from a branch office to HQ.

I have DSL Internet access with dynamic IP address + PAT at the branch office.

I have two VPN conc 3020 at the two ends.

What's the best way to configure a VPN between the two sites?

Many thanks in advance.

Thanks for the reply.

The tech. document does not completely reflect my scenario. Indeed, I need conc-to-conc connection not router-to-conc.

I think this is the real point. The concentrator at HQ cannot be configured to accept LAN-to-LAN from *any* in the list of peers. Anf this is required due to the dynamic IP address at the branch office.

Any idea or workaround?

Thanks
