I've installed OPNsense 26.1.6_2 on a Lenovo M720q with 5 NICS (built-in + 4 i226v PCIe).
I've followed every guide I've found to configure PPPoE, my ISP does not require VLAN tagging so I skipped that.
For some reason when the PPPoE connection is established, the device is getting an 10.x.x.x IP address instead of my public one. According to the ISP, when this IP shows as connected they see a connection.
Previously I was using a Cisco RV-345, when connected again it works. The ISP even provided me a set of testing credentials to see if it's an issue with the credentials.
Hi,
I'm not sure without logs and setup you employ, but this topic sounds similar:
