💡Mikrotik L009UiGS-RM Router Supports DS-Lite But Needs Manual Setup
Setting up Mikrotik for DS-Lite is tricky but doable
TL;DR
The Mikrotik L009UiGS-RM router supports DS-Lite, a strict form of CGNAT. However, setting it up manually involves configuring VLANs and cloning MAC addresses to authenticate with your ISP.
The Mikrotik L009UiGS-RM router now officially supports DS-Lite, the most restrictive form of Carrier-Grade NAT (CGNAT). This means no public IPv4 address on the WAN port and only a public IPv6 address. However, setting up this configuration manually is tricky and requires careful VLAN setup to authenticate with your ISP. If you're using PPPoE over VLAN 35 for fiber connections, you'll need to clone the original router's MAC onto the Mikrotik WAN port before speaking PPPoE. This impacts workflows involving remote access tools that rely on inbound connections or port forwarding.

Key Points
DS-Lite tunnel support on Mikrotik router, no automatic AFTR address reception
PPPoE over VLAN 35 used for fiber connection; clone original router's MAC onto WAN port
Run Ethernet cable from ONT to Mikrotik port 1 and set up VLAN interface before PPPoE
Create PPPoE client with ISP-provided username and password on Mikrotik router
Enable PoE output on port 8 for access point power without wall warts
Why It Matters
If you're setting up a home network with the Mikrotik L009UiGS-RM router, DS-Lite support means no public IPv4 address and only IPv6. This impacts workflows involving remote-access tools that rely on inbound connections or port forwarding. Ensure proper VLAN setup to authenticate with your ISP.
