Weird Problem with WAN?!

Username_is_reserved

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-interface

Then you will use your WAN IP

or you can set up a trunk with your PPPoE set by User Configured Trunk

With playing a lot with the Settings now it seem to work.
I dont know why that happen.

Is there an easy way to get to force an (Virtual) Machine an specific Wan Service who start with 100.X.X.X ?
Its because it would be nice to be behind the Virtual IP Adress from the ISP for some Machines to not expose my Fix Wan IP. (I will try to play around my self to.)
Thanks

EDIT!
I am happy to found it out much quicker as I tought. Its "that" easy by create a Policy Route. I will write an differen Article here.
