Lan Bridge

[hyp]

Hello I am new with opnsense and have some problems with creating a bridge for my 5 lan ports.
I followed this how to: https://docs.opnsense.org/manual/how-tos/lan_bridge.html#introduction

After adding the bridge to lan opnsense will crash every x minutes. When disconnecting wan everything is ok and opnsense will work "normal".

Hardware: Oroid H3+ with 4nic netcard (overall 6x2,5gbit ports, but at present only 1gb connected)
Config: To minimize problems with other configs I did a factory reset and only want to config the bridge first.

Thanks for helping in advanced!

Edit: Internet connection is dual stack lite

Did some forther testing. Opnsense is only crashing if a ipv6 address is served by my modem and bridge is enabled.

Anyone have idea whats could be wrong?

The interface connected to the modem (WAN?) is definitely not a member of the bridge?

Wan was correctly assigned. Problem got solved, dont know if it was the last opnsense update with new drivers and kernel or powering of every network device. Thank for helping anyway!
