Hello

I have around 7-8 vpn tunnels between zyxel USG60W , Azure, zyxel flex, etc

Even if I see vpn tunnel established, there is no inbound traffic through the tunnel.

This is totally random. Today there is a vpn tunnel not working , next day another one, after restart the vpn tunnels which worked do not work anymore, etc

What is the problem ? Is there any fix for this?

    Hi @Radu_Stanila ,

    Thank your time today.

    USG60w has some problem when decryted ESP header, so the traffic doen't reach the peer lan correctly.

    Now works fine after switching to AH.

    Please feel free to contact me if any concerns. Thank you
