Multiple IPsec connections of a single configuration

Hello,

I use Zyxel FLEX 100 with firmware 5.41.

I noticed multiple IPsec connections of a single configuration. It looks like this in the VPN stats monitor:

Why there are multiple connections for the MASTER_VPN_VLAN200 configuration? Any advice is welcome, thank you.

There are 2 configuration using this IKEv2 gateway:

MASTER_VPN:

MASTER_VPN_VLAN200:

Gateway configuration:

There is pfSense on the other side of the tunnel:

I think the problem is you have one gateway for the two VPN connections

If you setup two gateways each with different encryption or local/remote ID for each VPN connection it should work better.

Thanks @PeterUK, that would be a solution too.

Meanwhile, I found this option in the pfSense configuration, which seems to solve the issue:

The similar option is also available in the Unifi Gateway Network app.
