NAT breaks Windows update

[mlangendoen]

Hi all,

After upgrading to 25.10 Windows update is not working anymore for devices that are behind NAT. Device that do not NAT so only routed and firewalled have no problems.

anyone a idea?

Not sure if you are still experiencing a problem, but you'll have to do better at explaining your situation.

EVERY device using an IPv4 address behind a firewall/router is NATTED.  The major function of a router is to handle NAT.  If you are having problems with devices behind your firewall/router communicating with "the internet", it is due to a configuration issue.  Hopefully we can help solve it, but you'll need to give us a lot more information before anyone can start to guess what the problem might be.
