Thread moved to Networking since it's more about router configurations
Whilst my office uses a Draytek 2920 Dual Wan router, with VM business cable and an ADSL connection, we only need a single IP range internal LAN, and we don't really have any public facing services hosted locally. However the Draytek router appears to work well, for our 20 odd user network.
Are you having a specific configuration problem, or just need to know if it will work?
