Hi @Antonio_Rivera ,
It appears you have multiple NAT running which means that both the router of your ISP and your TP Link Deco perform NAT. You can read about multiple NAT and how to solve it in this article:

Hi @Antonio_Rivera ,
Welcome to the forum.
I agree with @Joost_Hoogland that there is a multiple NAT in your setup.
When i look at the error message i think your ISP is using CG NAT. I think it’s CG-NAT because the router_external_ip starts with 100 .
See below article for what CG-NAT is.
draytek.co.uk
DrayTek - Routers, Firewalls, Switches, Wireless Management, 3G/4G and IP PBX products
In this article you will see this:
Recognising GCNAT Address Ranges
CGNAT has its own reserved IP range between 100.64.0.0 and 100.127.255.255.
You could contact your ISP and ask the following questions (don’t made this up myself, just copied from @benjamin - Roon Staff: Technical Support).
Have you implemented carrier-grade NAT for my account level?
Have you fully implemented IPv6, or do you have IPv4 addresses available?
Can I request a static IPv4 address to support port forwarding?
Are there any ports you have reserved at the ISP level I should be aware of?
Hope it helps.
Kind regards,
Maarten.
