MBX HA (High Availability) not working as expected

Howdy Pepfolks,

I’m working on a MBX High Availability design, but things aren’t quite working as expected.

Clients connected to the MBX that’s in slave mode (with establish connections enabled) do not get a connection unless it takes over the master role.

Is there some hidden checkbox I’m missing to make this work?

Thanks!

Hi…

Maybe another colegue will have another sugestions…

But… When I build the HA solution for Peplink devices…
I had a managed L2 switch " split by vlan access " ( LAN ports ) and other WAN ports " again, split by vlan access " between both peplink devices.

like this, but using a dummy switch… just a sample for lan side… and you need the same for wan side.

Do you have the MBXs directly connected to each other for the heartbeat?

If so it will not work as expected, you need to have a switch between the MBXs so that the LAN port stays live and its can still attempt heartbeat requests or it sees it as both down.

Yep, the red cable is intended to be the HA/VRRP heartbeat.

However this got me thinking, the MBX is essentially a router with an 8 port managed switch, so conceptually it should be possible.

After some further experimentation, setting all 8 LAN ports to access with a VLAN, with WAN3 set as the trunk/untagged appears to work!

Nice, glad you got it working.
