3. Configuring the DSL Router

If the DSL interface IP address changes, the Basic NAT static mapping that conflicts with the new DSL IP interface address and all Basic NAT dynamic mappings are removed.

If the IP Passthrough feature is used, the DHCP Server feature is automatically enabled and the negotiated IP address is the only IP address served. In addition, the derived subnet mask, discovered peer IP address, and negotiated DNS server addresses (unless explicitly directed not to use the DNS addresses) are configured as the DHCP options provided to the client.
