      Okay, so with default IPSec, there's no chance to hand out fixed IP addresses and therefore no possibility to attach specific access rights?
      I'll probably stick to the simple enable-on-request solution then. Thanks!

        There is such an opportunity for Road Warriors
        What authentication method is used ?

          We authenticate via Active Directory. "Pre-Shared Keys" as in your screenshot is empty in our pfsense config.

            It doesn't matter
            You can fill in this field with any characters, as long as the user ID matches
            This creates a config for the user "engineer" and assigns the required ip address

              @luas For example
              I have authorization configured on the certificates

                @Konstanti Thanks!
                I tried this, but with no luck.
                I used "username" or "username@domain.local" as Identifier, entered a Pre-Shared-Key and a specific IP-Adress with mask /32.
                But I will still get an address from the default pool.

                I also tried to configure a unique PSK for the engineer in the given dialog, but then the tunnel won't come up at all.

                Any other idea?

                  And what is the ID of the engineer ?

                      If the problem is still relevant, I think I know how to solve it

                          t's easy , but you need to work with your hands a little .

                          1. create a file on the firewall , for example, /usr/local/tmp/ip.sh
                            make it executable, chmod +x ip.sh)
                            Write on there such the text

                          0_1547906340263_d3c90542-b90c-4b2b-9038-8372cf693592-image.png

                          Save

                          1. /diagnostics/edit file/ etc/inc/vpn.inc
                            Find here is such a string
                            if (isset($ph1ent['mobile')])) {
                            Adding here is such the text
                            $ipsecfin .="\tleftupdown=sh /usr/local/tmp/ip.sh\n";

                            0_1547906566190_2649f0b6-288f-4873-a920-4093a42d43f0-image.png

                          Save

                          1. vpn/ipsec/ mobile client /phase 1/ not to change anything . Click Save, exit

                          2. /diagnostics/edit file /var/etc/ipsec.ipsec.conf
                            0_1547907106048_10d9505b-2a45-45d7-bdb4-cb7d7a57c24c-image.png

                          Make sure that everything is correct

                          As a result at us at an input of the user "konstanti" the script which gives it the rights of connection only to a host 192.168.15.6 works , other traffic is blocked. No matter what virtual ip it gets.
                          Other users work without restrictions

                          In your case , we change the username to "engineer ID" and adjust the rules so that it has limited access.
                          This can be done for any user
                          The only caveat that we need to know .
                          With every system update , the file vpn.inc will be overwritten and changes will need to be made again

                            Or you could just use FreeRadius like I suggested and not have to mess about with text files.
