Hi kenshipp,
I have searched online about the Zyxel USG40 and found out from its user guide here that its default LAN subnet is 192.168.1.x. The default LAN subnet on the FVS336Gv2 is also 192.168.1.x. Because of this, you will not be able to fully establish a box-to-box VPN connection. You will need to change the LAN subnet of either the Zyxel USG40 or the FVS336Gv2 to a different one. For example, since the FVS336Gv2 has a LAN subnet of 192.168.1.x, you may change the LAN subnet of the Zyxel USG40 to 192.168.9.x or 10.10.10.x.
Let me share the articles below and use it as reference guides:

Hope this helps.

Both LANs have been changed to different subnets long ago.
Thanks for the response.

Thanks for the feedback. :)
Kindly check the SA Lifetime values. Let me share these old forum links below that might help as reference:

If ever it does not help, kindly post screenshots of the VPN settings (such as IKE & VPN Policies) configured on both FVS336Gv2 and Zyxel USG40.
