General Discussion / Firewall WAN IP is seen differently externally?
« on: March 31, 2024, 11:54:07 pm »
Apologies in advance if this turns out to an obvious one, but currently baffling me.
The WAN interface on my firewall shows as 100.73.x.x, and when I look at the logs this is what also shows as itself. When I take PCAPs, this is also the same.
My Dynamic DNS though is reporting it as a completely different address 188.74.x.x. I may have thought this is an error, but I have a wireguard site to site VPN with another opnsense firewall, and it sees this end as 188.74.x.x as well?
I am trying to diagnose an issue where traffic doesn't seem to be reaching this firewall i.e. when looking as logs, pcaps and SSH'ing or HTTP'ing to 100.73.x.x its not showing up. I am currently working abroad and trying to get my wireguard VPN working, and for all testing I am doing it just doesn't look like its reaching the firewall.
It used to work, and have recently changed my ISP, so might be related? Just can't make sense why the firewall thinks its one IP address but other devices see it as something completely different?
In either case, using either IP, I can never seem to see traffic hitting the firewall I generate either in logs or PCAPs?
To me this seems illogical or not making sense, but hoping someone has an answer or something for me to try?
