VPN3000 and dynamic dns

I'm asked to build a l2l tunnel with a sonicwall TZ170 which has a dynamic public address, providing that this device cannot behave like an easy vpn client, is there a way to tell the vpn3000 to accept a fqdn as a vpn peer or to configure a 0.0.0.0 as the peer address of a l2l vpn?

Bye,

Max.

Re: VPN3000 and dynamic dns

Dynamic DNS (DDNS) allows automatic registration of VPN Client host names into a DNS server upon successful negotiation of the VPN connection. When a VPN Client initiates a connection, the local host name is sent to the concentrator, which in turn forwards this onto the centrally located Dynamic Host Configuration Protocol (DHCP) server for the address allocation. If the DHCP server supports DDNS, then the allocated address and host name are entered automatically. DHCP address allocation is a requirement for DDNS to function, but does not work with local address pools.
