I've just replaced a BT Homehub with a 2820N to allow better VPN to my office. However, whereas the BT Homehub allowed me to use host names to access other stuff around my lan, such as cctv camera, NAS, other PCs etc, I am having to use ip addresses with the 2820N. Ping returns "Unresolved host" messages. I haven't changed the firewall filters, just set up a dialup VPN client and a lan to lan config for the office, and blocked limewire etc. This is with both 3.3.0 UK and the newest 3.3.1 UK firmware.

Ignore this - the problem is with my PC - all the other PCs work fine using host id rather than ip address.
