Welcome! Here’s a revised version of your message:

I’m updating my home network setup. I have a VDSL2 connection arriving at my residence. My ISP provides a modem/router that supports VDSL2 (ZyXel VMG3925) and an Ubiquiti Edgerouter X. I’d like to set them up so the ISP device functions as an "internet adapter" while the Edgerouter handles routing. The ZyXel modem/router is currently in bridge mode, and the Edgerouter remains in its default factory configuration.

I’m presently accessing the internet through the ZyXel’s WiFi, even though it’s in bridge mode. The WiFi works fine. I also have an Ethernet cable connecting to the Edgerouter, allowing me to access its interface, but the wired connection isn’t linked to the internet. There’s a patch cable from the ZyXel’s LAN1 port to the Edgerouter’s Eth1 port. Are there specific adjustments needed on either device? Or should I connect Ethernet cables to certain ports for proper operation? Any guidance would be greatly appreciated. If you need more details, feel free to share.

Your internet service provider doesn’t currently offer bridge mode support. Changing their modem or router to bridge mode usually results in losing internet access. In the Edgerouter interface, there’s likely a setting to specify which port is designated for WAN—often eth0 defaults to that role. This port would connect directly to your modem. It should receive an IP address from your ISP’s DHCP server. However, they might not assign one automatically, which could explain the connectivity issue.

@Mikke I share the same view as @Eigenvektor. Confirm your DSL gateway is compatible with bridge mode. After enabling it, connect it straight to a PC's LAN port and verify the WAN IP appears in adapter settings. For the ER-X model, don't install it immediately—use the setup wizard first. Specify which port connects to WAN and how to handle the remaining ports. Typically, eth0 is designated for WAN while others serve LAN on the same switch. Check the YouTube tutorial for detailed steps covering static IP assignment, firmware updates, and final router configuration with SQM improvements. Also consider enabling hardware offloading for enhanced performance.
