Title: Need help to configure my FTTP
Post by: hushcoden on February 22, 2026, 01:15:14 PM
I'm currently using an FTTC connection with PPPoE, and in the next few days, I will be switching to FTTP (still PPPoE). I know where to enter the username and password - Interfaces -> Devices -> Point-to-Point - but for the life of me, I can't find where to enter the static IP address the ISP has provided me (along with the subnet mask of 255.255.255.255).

Tia.

P.S. - I'm running OPNsense v25.7.11_9.

If you have PPPoE the ISP will assign the IP address when the connection is initiated. Your OPNsense does not need to know in advance. Static or dynamic is a contract matter in the PPPoE case, it's still always ISP assigned.

Thank you, good to know that I just need to change the username and password, and that's it.

You also need to know if your ISP wants a specific VLAN tag or not.

Me again, today I switched to FTTP, but I cannot browse the Internet, and ISP confirmed I don't need any VLAN/Tag.

The interesting thing is as soon as I run the VPN on my laptop, I can browse, whys is that?

I suspect it might be a DNS issue because if SSH to the OPNsense, I can ping any sites with their IP addresses but not by name.

Does it have anything to do with the fact that I now have a static IP?

Can someone help me to understand what the problem may be?

Update: after rebooting the ONT and 4 times the OPNsense appliance, it works now.
