Please add support for FQDN in VPN setup

[frogfoot]

Hi I use a 7800N and connect to another router via VPN, Currently there is no method to add a FQDN to the 'PPTP Server Address' when setting up a VPN. This causes me no end of problems as each time the router at the far end reboots its IP address changes requiring me to ping the FQDN to find out the new address and then to change the configuration on the Billion.
