Tutorials and FAQs / [Tutorial] Bridged Modem Access Guide
« on: April 12, 2023, 10:53:34 am »
Hello everyone,
After a lot of attempts I finally managed to setup my a access to my modem over bridged network, So now Imma gonna show you how to set it up so you'll don't have to figure out by yourself
First of all we need to understand a few things:
Let's start on Modem Side
On our Modem we would need to setup the interface for our needs, for me I had the network set to subnet of 30 and an IP address of 10.10.10.10 like you see in the picture:

also I disabled all of the unwanted stuff from my modem like IGMP and DHCP cause we are not going to use it, make sure that you don't place the same IP both on the FW & the Modem cause it will not work.
Let's start on Firewall side
First of all we need to set up the same NIC as the WAN port that we use for the bridge router as shown in the picture:

As you can see I have under interface assignments two igc0, One of the is for the WAN (PPPoE) & the other for the Modem which I'll explain now how to set.
Now under interfaces we need to enable the new interface and name it however we want, I recommend Modem which will help you follow along, The settings we setup:

Change the IP address to a Host IP, for example if my modem GW is 10.10.10.10/30 I'll use 10.10.10.9 for it cause our network has only 2 usable IP addresses (Our Network Address is 10.10.10.8 & Our Broadcast Address is 10.10.10.11 which mean we could only use 10.10.10.9 - 10.10.10.10).
Now we need to set NAT for our network to traffic out \ in so we could get that juicy GUI
We would go to "Firewall" -> "NAT" -> "Outbound" and we will add the following:

Now for the last step which would enable the GUI!!!
we would need to go to "Firewall" -> "Rules" -> "Floating" and we will add the following:

Basically if you had copied all of my settings from before you would just need to set it up like this, if you changed some stuff adjust the settings according to your previous steps.
Glad to help and if there is any questions please feel free to ask me out

First of all we need to understand a few things:
- We run our modem over one cable to the OPNsense FW WAN port.
- We split our WAN (May only work with PPPoE, Haven't tested it with other options so share with me if it works)
- We set it up so we would have the GUI access to our Modem.
