[[6.12] Networking not working correctly after upgrading to 6.12 and changing docker to ipvlan]

I'm not using docker exclusive IPs as far as I know?

 

 

root@Tower:~# docker network list
NETWORK ID     NAME       DRIVER    SCOPE
76bd4672c776   br0        ipvlan    local
f16d1d53f08a   bridge     bridge    local

Hi, yes my unRAID server has a static IP address already.

 

Would be nice to know what "features" the home router specifically needs to support ipvlan, I've had a dig around and can't find any specific feature/support that it needs?

 

I am running OpenWRT on my router so it's pretty flexible.

I found the fix to the 40 minute losing external connection issue on 6.12.0:

 

I set "Host access to custom networks" to disabled and since then the network has been fine.

 

I will install 6.12.1 anyway

Just done another reboot on unRAID, everything worked fine for a period of time then after approx. 40 minutes unRAID seems to lose external access.

I can ping my router fine, and in fact Plex is still working.

 

It *seems* to be just affecting unRAID:

So, running with IPvlan and IPv4 networking for a bit and everything was fine.

 

But now, unRAID seems to have lost access to external networks, eg:

 

 

Here are some more logs if someone can look please?

Still having same issue and I was already set to ipv4

May be a slightly different issue from mine then, worthwhile starting your own thread with diagnostics

[[6.12] Networking not working correctly after upgrading to 6.12 and changing docker to ipvlan]

OK, so think I figured this out.

 

My unRAID networking was set to IPv4+IPv6 due to SMB related networking issues I had in the past.

 

Changing the network type to IPv4 seems to fix this issue.

 

I tried this due to a comment I saw about IPvlan use "Finally, auto-configured EUI-64 IPv6 type addresses are based on MAC type addresses. Therefore, all the Virtual Machines or containers that share the same parent interface, will auto generate the same IPv6 address. We advise the user to make sure that all the Virtual Machines or containers use static IPv6 addresses or IPv6 privacy addresses with SLAAC disabled."

 

Whether the above is root cause I have no idea but IPv4 is working so far with IPvlan.

 

Whether my SMB related network issues now return I will have to see....

Any reply support ?

Just to add I've spent a considerable time today trying to figure out why Plex could no longer communicate with tvhproxy, turns out this bug is the reason.

 

I did a reboot of unRAID and all started working again.

 

This should have a priority of Minor at least, not Annoyance as functionality is affected.
