February 25, 20233 yr Community Expert Hello! Ive been noticing that my ipv6 changes everytime i reboot the server or it fetches its new ip. Ive tinkered around and noticed that the bridge feature is the culprit that assigns br0 a random interface identifier everytime. (privacy extentions are set disabled) Is there a way to force a permanent interface identifier without disabling the bridge function? I do need a stable interface identifier on that machine 😓
March 6, 20233 yr Author Community Expert Solution Wanted to give an Update. I actually found a solution to my surprise. I recently bought a USB3 to Ethernet Dongle and just shoved it in there. It supports being bridged and to my surprise, now it acutally keeps the same IP6 Identifier. So this is a single NIC-Bridge Problem.
March 31, 20233 yr Author Community Expert Small or big update, depending how you see it: Ive found a way to "cheese" it, that does not require a second NIC All you need to do is change to the following settings in the config/network.cfg and it magically works! BRSTP[0]="yes" Im really curious what the BRSTP setting actually is. Since it is required to be set to Yes, which defaults to No. This might be a bug, because the Yes only appeared after i bridged two nics. Might be the privacy extensions part, idk. But hey. It works, it gives out the static identifier. (What ive noticed with my Fritzbox, you need to enter a "Ghostnic" in BRNICS[0], so it looks like BRNICS[0]="eth0 eth1" for some reason, if you dont do it, the portforwarding for ipv6 is absolutely broken. Could also be just the case of ipvlan being set, macvlan is the choice for that router. Anyway, it works regardless one way or another. ) Edited March 31, 20233 yr by Mainfrezzer Added some observation
