A British ISP recommends using the DLINK DSL-320B in bridge mode only: "... bridge mode for use with a PPPoE Router. Supports 1508 byte "baby jumbo" frames for full 1500 byte MTU PPPoE operation. ..." http://aa.net.uk/broadband-accessories.html "DLINK 320B PPPoE Bridge Modem, ADSL * Use with a your own PPPoE router/firewall * Can do full 1500 byte MTU over PPPoE, which the ZyXEL can't in bridge mode * Don't use it for anything but a bridge! * Native IPv6: n/a (as used as a bridge)" http://support.aa.net.uk/Help_Choosing_A_Router How they deploy 2 (+ another spare) ADSL modems for failover. You would be building the brick thing instead of what they supply: http://www.aa.net.uk/broadband-office1.html Their MTU explaination page: http://aa.net.uk/kb-broadband-mtu.html Their "How Broadband Works" page (British Telecom - usually PPPoA): http://aa.net.uk/kb-broadband-how.html
