I'm probably just a bit stupid, but here we go. I have Opnsense set up and working great. I was with sky broadband, and switched to 2degrees to take advantage of a better price for a year. I requested a static IP which was apparently assigned, but I'm still getting a CG-NAT IP address. I've rebooted the ONT, and the OPNSense box, but it's still not showing the static IP.

I didn't think I'd need any changes in OPNSense once it was switched, but it will not recieve the IP I've been told was assigned (101.98.x.x) and is instead getting one from the pool (100.67.x.x)

I did try changing from DHCP4 to Static and adding the IP but it didn't connect.

Any suggestions for what I'm doing wrong here?

Photos attached (ignore the wan name I just haven't changed it from sky it makes no difference)

You could try setting the MTU to either 1492 or 1500 but I don't think that will change anything. Based on the device name on the wan interface I can tell that you're VLAN tagging the interface and that would have been previously configured for Sky Broadband. Normally you wouldn't need to change anything and just reboot your router.

Might pay to give 2D another call.

Do you have another router you could do a test with, or can you connect a PC directly to the ONT?

It's tagged VLAN10, the name is just from the initial setup, and I haven't changed it.

I don't think the MTU will make a difference but I'll give it a shot.

I'll see if I can dig out an old fritzbox or something and give that a shot as well. Cheers

I'll call them again on Monday, thank you. It's been a bit frustrating getting through to them. Thank you.

One of the very helpful members here was able to cycle me on 2Degrees end and everything is working properly now, and the static is there after re-authentication. Thank you so much!
