Weird Problem with WAN?!





Well I dont know how but since my ISP Upgradet my Internet to an higher speed everything is weird… No HW changed. I also use the Zyxel Modem from my ISP. The "Dial In" does my ATP.
When I go to Ethernet i see this:
The show me an 100.X.X.X IP Adress as WAN IP.
When I go to PPP I see this:
Here I see my fix Wan IP Adress startet 185.X.X.X that is the one who I got from my ISP to access from WAN into my System.
Now the weird thing! When I going to any IP checking Site now the show me an 185.17.X.X IP Adress?? Where does the come from? (Yes it is NOT my fix WAN IP)
So where do I set something that the ATP using my fix WAN IP? So embarrassing. 😪

Don't know much about PPPoE and think I would not like how it works.
So the WAN is getting 100. which I guess is 100.64.0.0–100.127.255.255 ? used for CGNAT my guess is you are SNAT off this from some WAN IP that is not your WAN IP by PPPoE
If you make a routing rule like
incoming any or LAN
nexthop your PPPoE interface
SNAT outgoing-interfaceThen you will use your WAN IP
or you can set up a trunk with your PPPoE set by User Configured Trunk
