March 25, 20251 yr Hi everyone, I've been having some issues lately with getting IPv6 networks from my VLAN interfaces into Docker. So far I have not found the root of the issue. On my interface eth1 I have VLAN 10. On this I enable IPv6 with SLAAC and disable the default gateway. The network is already selected on the docker page. It's good to note that when I unselect it and click on apply, it reappears as enabled. Inspecting the docker network reveals that IPv6 is still disabled. I have had this working a while back, I'm not sure when this stopped working. When I run a docker container with "--sysctl net.ipv6.conf.all.disable_ipv6=0" the container gets an IPv6 through SLAAC. Does anyone have any pointers as to where to look? Thanks in advance.
March 26, 20251 yr Community Expert Update to 7.1.0-beta.1 and retest, there are some IPv6 changes there.
June 25, 20251 yr Using 7.1.4 here. My unraid has ipv6 connectivity. My VMs have IPv6 connectivity.Everything I've tried so far gives only IPv4 connectivity to dockers. Specifically, I'm trying to give the sftpgo docker IPv6 connectivity.Searches have shown that docker has or HAD extremely poor IPv6 support, so I don't know if this is an unraid or docker issue.I've found reports that IPv6 traffic is dropped going to br0, but it was fixed early in unraid 7 with a docker update.I've tried giving my docker static IPv6 through br0, and it still only gets an IPv4 address.I've tried giving my docker host networking, and it doesn't respond to IPv6 requests.Any help would be appreciated!!
June 25, 20251 yr Update: I was able to get it working by setting the docker to use host networking.Through trial and error I found that:1 - the sftp port setting in the docker for sftpgo doesn't change the listening port. ergo, the port you thought you set it to isn't the real port.2 - the unraid docker dashboard doesn't show the docker listening on the ipv6 address of the host when the host is configured for ipv6 and the docker is set to host, even though it is. This seems like an unraid or docker bug?
