      I see I can specify a VLAN for a FreeRadius user.

      Can this be used to control what a user can access via FW rules if each VLAN has it's own interface?

      For example:
      Any user connected with VLAN ID:10 can only access server A and any user connected with VLAN ID:20 can only access server B

        @McMurphy yes you can can limit what what device in network A can talk to in network B. But you can not control what device in network A talking to a another device in network A.

        Where are these servers these users/devices will be talking too?

          The scenario is we have multiple users connecting to our LAN via VPN & FreeRadius.

          I wanted to group users to restrict what each group can access

          To date I have done this with with multiple OVPN servers and FW rules. One OVPN server for each group.

          I had the thought of using a single OVPN server and then use the VLAN ID in FR to control what the users can access, once they are connected. Using FW rules.

          The users are home users and the servers are on our LAN behind pfSense.

            In the FreeRadius certificate you should be able to set up also the VLAN(x)
            so this user is then even at connecting into that vlan in.

              @McMurphy not sure why you need multiple vlans or networks to do such a thing.. Give user A IP address X when they connect to the vpn. Control where ip X can go with some firewall rules..

                100 users connecting to 5 servers only needs 5 VLANs so 5 FW rules

                Is that not less admin than assigning each user an IP and managing these 100 IPs with rules?

                  @McMurphy you didn't say 100 users in your post ;)

                  But you understand 1 vpn server can listen on multiple ports.. So have one that listens on 1194, 1195, 1196, etc..

                  Users that connect to 94 can connect to whatever you want them to, setup 95 users to connect to whatever other things you want those users to connect too, etc.

                  But if you control what specific IP a user gets you have the flexibility to easy give them access to whatever you want, and change that on the fly if they then need access to something else. And not have to have them connect to different networks or be giving everyone else that connects to that vpn access to the same thing, etc.

                  But you don't need 5 vpn servers you only need 5 instances of of vpn running..

                    Apologies, could be 200+ users in the future so looking for a solution that is easy to administer.

                    If I use ports to control access the could a user not simply edit the port in their OVPN profile?

                    If I am going to assign a value to each user then I think the VLAN option is simpler, if it works...

                      @McMurphy they can change the port, but its a different instance - they wouldn't have the login. Or the cert - these are different instances.

                        I am sorry however I cannot understand how a single VPN server can listed on multiple ports?

                        I have checked my OVPN server and see a fields entitled Local Port however it appears to only take a single value. I may be mixing up terminology but what is the difference between an OVPN Server and OVPN instance?

                          I can give the user a VLAN in the FreeRadius settings but not sure how to use that in the FW rules.

                            If I give each user a unique IP address in FreeRadius, is this an address from the OVPN IPv4 tunnel network?
