Do you authenticated account by LDAPs? Zyxel device doesn't support SAML( Azure AD) but support LDAPs(Azure AD DS), so that need to use Azure AD DS integrate with Azure AD. I am not sure do you mean you NAT to internal Server with RDP service, and login fail if authenticated by AZUREAD account? The "Local account" do you…

If use IPSec VPN client application, even the port 443 was occupied, the VPN should be connected, since as mMotana mentioned, IPSec VPN client running service port(500, 1701, 4500 UDP). Was the Error message "server not available" from the log message? If so, share the screenshot of the log message which related with VPN…

I think you can try to enable connectivity check to avoid the tunnel down. Configure connectivity check on Client side, and the Check IP you can set IP of Lan device which behind USG40 1: server side.

It's very old model. I think the document is all English version. You may check with local zyxel if you have problem

Some users faced the issue but others works fine? Not sure it's over number of device handling. What firmware do you use?

Need to add policy route on both sides. EX: On site A, Source:Local Subnet(A,192.168.0.0/24), Destination: Remote Subnet(B), Next Hop: VPN tunnel, Select the name of VPN rule On site B, Source:Local Subnet(B), Destination: Remote Subnet(A,192.168.0.0/24), Next Hop: VPN tunnel, Select the name of VPN rule

For my point of view, the set Google wifi in bridge mode, and USG in NAT router. Therefore, you can let wifi clients communicate with Lan2 client via routing.

Cannot the all client access internet with default DNS setting? Since your configuration is not too complex and firmware is previous version, I suggest you update the latest firmware and reconfigure it again.
