So I’ve started rolling out VyOS and IP in IP tunnels, to test the performance vs GRE tunnels. And there is a noticeable difference in the speed. Which is great!
However, the test site, my office where I am located. We have users whom have left their PC’s on for a while, and when we pushed out the latest Windows 10 Feature Updates, they were restarted. Of course initially we thought that it was related to the Feature Update, but nope this was an issue else where.
Basically when we configured our dhcp-relay, using information that we have obtained across the interwebs and these forums.
- We configured the interface that was connected to the clients into a bridge port.
- We then proceeded to configure the dhcp-relay client as per the Wiki, specifying both the tunnel interface and also the bridge interface.
- Specified DHCP server.
So no DHCP packets seem to be passed onto the DHCP server and replied. No firewalls are currently configured at this stage.

Confused as hell! Because in a previous release of VyOS 1.1.7 I think or 1.1.6, it worked perfectly.
I read somewhere that someone got it working over tunnels. So would be good to know or find out what was done to get it working.
