[rbak-nsp] Problem with assigning static ip address with pppoe

[Robert Lipiński]

hello
I question whether there is a possibility of granting permanent ip address 
for the PPPoE client.
my config looks like this:

subscriber name 1234
    password 1234
    ip address 172.23.0.11/27
    ip route 10.10.8.1 subscriber
    Policing policy qos-up wifi
    qos policy-down metering wifi
    nat policy-name NAT_policy
    ppp mtu 1492
    178.212.120.1 primary dns
    213.199.225.14 secondary dns
However, after logging a client gets an address from the pool next:

1234
         Circuit 2 / 1 vlan-id 24 pppoe 17
         Internal Circuit 2 / 1: 1023:63 / 6/2/17
         Current port-limit unlimited
         ip address 172.23.0.2 (applied)
         0.0.0.0 10.10.8.1 ip route 172.23.0.2 (applied)
         ppp mtu 1492 (applied)
         dns 178.212.120.1 primary (applied)
         213.199.225.14 dns secondary (applied)
         Policing qos-policy-wifi-up (applied)
         qos-policy-metering wifi-down (applied)
         nat policy-name NAT_policy (applied)

Interface configuration:
  pppoe interface multibind
   ip address 178.212.127.193/26
   secondary ip address 10.10.8.1/24
   secondary ip address 172.23.0.1/27
Thank you in advance for any suggestions and additional information
