Peplink PEP VPN (anyone can help)

Hi, Good Day!
i just want to ask if this is possible that the user can access the webserver based in the diagram through a pep vpn tunnel.
note:
* webserver can only be access through a public IP ADDRESS defined by the
host
* only the peplink balance 380x has a public IP ADDRESS

thank you in advance for the help.

Yes that will be fine. Add an outbound policy on the B20X to send traffic to the web server public IP via the PepVPN tunnnel.
