Limit access to only one IP via OVPN RW

NethSecurity

Good morning everyone, I installed netsecurity 8 for the first time and everything is ok. Now I needed to give access exclusively to a single IP on the LAN, via an OpenVPN. Can you suggest me the best procedure to do this? Thank you

Firewall rule?

Thanks for the reply, that’s what I tried to do but I can’t formulate the rule. I probably haven’t gotten the hang of it yet since it’s my first installation. I created an object (the server to reach in LAN), I created a fixed IP to assign to the user who must connect in VPN; but when I go to create a rule I can’t find a way to set the server as the only destination reachable from this IP…

According with documentation…
https://docs.nethsecurity.org/en/latest/firewall.html
this should be part of Forward rules tab. And three rules, IMVHO, should be written.

  • from VPN IP to server IP: allow.
  • from VPN IP to internet: allow (optional, only if you need/feel correct that the VPN user should use internet via the WAN of the firewall)
  • from VPN IP to anything else: deny

However.
Input rules and output rules I don’t know if they are processed before or after the Forward rules (IMVHO before, but there’s no clear indication of the process order).

And last but not least: would you kindly share a look-a-like screenshot of what you find confusing? :slight_smile:
