Couple of things to be aware of, the DrayTek in bridge mode is not the easiest too setup. Draytek engineers have missed the point that the when the 166 is operating in bridge mode the unit has two functions.
1) Create a PPOE connection between router ( or PC if no router used) and DSL connection.
The default VLAN tagging of 101 should be left untouched, it is needed for a connection via BT Infinity infrastructure.
2) Create a local LAN connection to be able to manage to unit either via web guide or SSH
It is the second function that is not handled properly via the setup functions available. I have submitted bug reports to DrayTek about 5 month ago, but have not seen a reaction to table the issues besides a message from the first line support person that the issues have been passed on to engineering.
It can be done taking the following steps.
First make a direct connection between her PC and the unit to change the default unit's IP address to an address that matches your local LAN subnet. This van be done via the web GUI under LAN -> General setup in the left column.
Next steps can best be done via command line. Use ssh to get access, ssh admin@<dtraytek ip address>
After entering the admin password you get access to the commend line.
Things to resolve/setup is
1) Routing to your Internet gateway/router
2) ntp set up, it is good to have correct time stamps on logging/error messages
The first step is critical for getting admin access from your LAN to the DrayTek, ntp is good to have.
1)
Issue the following command;
ip route add 0.0.0.0 0.0.0.0 192.168.0.1 0 default
where 192.168.0.1 is the LAN GW IP address , in this case 192.168.0.1
ip route status
Codes: C - connected, S - static, R - RIP, * - default, ~ - private
S~ 0.0.0.0/ 0.0.0.0 via 192.168.0.1, IF0
C~ 192.168.0.0/ 255.255.255.0 is directly connected, IF0
Next this is NTP;
sys time server
sys time server <domain>
<domain> max length: 39 bytes., domain is the server ntp name or IP address
To check the settings:
DrayTek> sys time show
