@thinkl33t, recommended way is using dynamic-dns-update, all other ways are not recommended to use at this moment.

Yeah, I'd mark this not-a-bug. Update the documentation to mention hosts file update with failover doesn't maintain consistent state between failover servers.

thinkl33t added a comment to T1076: Configuration files are kept in the system when VyOS config is commited but not saved.

Could we work around this by implementing an overlay for every commit, with the entire stack of overlays being combined with the root overlay when a save is issued?

I've finally managed to test this (apologies, we've had a super busy couple of months) and don't appear to be able to connect to the VPN anymore :(

I've put in the suggested kernel parameters for my install to disable the broken functionality. Hopefully this will keep it stable until a version with an upgraded kernel is available :)

Note that this has taken down DNS on our firewall (and hence our network) a couple of times now, both annoyingly early in the morning when nobody was in to fix it.

thinkl33t added a comment to T659: Static DHCP mappings aren't available on DNS.

I've implemented this in our ansible-derived vyos configuration by allowing the static addresses to be generated with the VLAN prepended and adding a system static-host-mapping for the fqdn to ip.

I've done a bit of fiddling with this today on a test VyOS 1.2.0-rc6, Attempting to set a custom option and pass it through to the leases file. Unfortunately I wasn't successful.
