How do I access the modem part through the router?
I've got a Draytek 130 Modem and a Ubiquti USG router how do I configure it so I can access the modem through the router ?
Can anyone help ?
Info below is based on my setup. Please be aware that any unsupported configuration you make on your equipment could render it unusable.
I have a similar setup with a Draytek Vigor 130 and an Asus DSL-AC68u router.
In my setup, if all network settings have been left at default, then the IP address of the Vigor 130 interface admin interface will be 192.168.2.1.
The Asus router will have its internal network as 192.168.1.*. The router admin interface will be 192.168.1.1.
So, the internal devices will have IP addresses in the range 192.168.1.2 - 192.168.1.254.
To route traffic between the 192.168.1.* and 192.168.2.* networks (which is required to access the Vigor 130 admin interface), the ethernet port on my Asus router which is connected to the Vigor 130 needs to be in the 192.168.2.* range, so for example, it can have an IP address of 192.168.2.15 (or anything else in that subnet which is not in use).
My Asus admin web console does not allow me to set an IP address on any of its ethernet ports (including the one connected to the Vigor 130). So I had to launch a terminal session and connect to the Asus, login as admin, and use the Unix based ifconfig command to first determine which virtual interface was connected to the Vigor 130 and then assign an IP addresss of 192.168.2.15 to that interface.
The router then updates its internal routing tables to allow it to route between the 192.168.1.* and 192.168.2.* networks. This then allows my devices on 192.168.1.* to connect to the Vigor 130 admin interface on 192.168.2.1.
It took a bit of trial and error to find the correct virtual interface which represents the physical port on the Asus router which is connected to the Vigor 130. Also, the config is reset if the router is rebooted, so I need to set the IP address after every reboot.
Your router may or may not work in the same way, but, hopefully, the above information might help you in finding out how to access the Vigor 130 admin interface in your setup without having to disconnect it from the router and then attaching a computer directly to the Vigor 130.
