Hi @Nimmiotheit93
You can enable DMZ-mode.
This way you can still mange all port-forwardings etc. on your router, as the Internetbox will forward any incoming traffic to it.
Which VPN-solution will you use?
Please note, that you will have to disable the integrated VPN-server on the internetbox, if you want to use IPSEC on your router.
Best,
