OPNsense Cluster UDP storm on WAN interface

[jandoe123]

Hey 

I have a strange problem with UDP packets on WAN interface (WAN called "Hybrid" in my config).
I have a active-backup cluster with carp and pfsync on two gateways.
node1 wan: 192.168.2.103
note2 wan: 192.168.2.104
My firewall log is full with this events on both gateways:

Code: [Select]

Block Hybrid 192.168.2.104 239.255.255.250:1900 UDP
Pass Hybrid 192.168.2.103 255.255.255.255:138      UDP

Both wan interfaces connect to a speedport modem/route from Telekom and get a dynamic ip from this router.

Can someone help me to stop this trafic?

Thanks!

Jan
