How I set two IKEv2 VPN connection on one VPN gateway?

BZS · July 2020

Hi!

I have a ZYXEL ZyWALL 110 firewall.

I try to set two IKEv2 site to site VPN connection (with two different local subnet) on the same VPN Gateway.

My problem is that the two VPN connection does not work at the same time. The first connection work, if I set inactive the second connection and the second connection work, if I set inactive the first connection.

What is the solution?

Thanks your answers!

Hi @BZS,

Welcome to Zyxel Community.

Two site to site VPN phase 2 connection linked to same VPN phase 1, it’s doable scenario.

Can you activate both VPN phase 2 connection and post device VPN connection log.

I would like to check IKE and IPSec VPN error log.

MONITOR > Log > View Log.

Key word x.x.x.x which is your peer firewall public IP, you can mask it when your post VPN log.

Hi @Zyxel_Cooldia,

The two site to site vpn phase 2 connection linked to VPN phase 1 works well, but the same time only two VPN connection can to do work on the firewall.
