hi there.
i have some computers that has firewall installed and I can see that the firewall blocks for UDP port 33281 incomming , the destination ip adress is the domain controller. but port 33281 is not a know active directory port, so what is going on!.

That query should be directed at the firewall supplier or to who ever configured the firewalls.

Doesn't make much sense that its blocking a incoming port but the distination is the server. These are workstations not firewalls.

the sender ipadress is the domain controller

which goes back to why block anything coming from the server?
Looks like its just a firewall misconfig by someone who didn't know better.

well, port 33281 is not a known active directory port.. and the server is domain controller and dns server.. nothing else
