[strongSwan] can't set dns on customers side

[Gregory Edigarov]

Hello,
 
strongSwan 5.6.2 on both sides.

server side config:

conn ikev2-vpn
    auto=add
    compress=no
    type=tunnel
    keyexchange=ikev2
    ike=aes256-sha1-modp1024
    esp=aes256-sha1
    fragmentation=yes
    forceencaps=yes
    dpdaction=clear
    dpddelay=300s
    rekey=no
    left=%any
    leftid=@example.my.domain
    leftauth=pubkey
    leftcert=certificate.pem
    leftsendcert=always
    leftsubnet=0.0.0.0/0
    leftfirewall=yes
    right=%any
    rightid=%any
    rightauth=eap-radius
    rightsourceip=10.255.255.0/24
    rightsendcert=never
    rightdns=192.168.12.2,192.168.21.2,192.168.111.2
    eap_identity=%identity



client side config:

conn ike-test
     auto=start
     fragmentation=yes
     keyexchange=ikev2
     right=example.my.domain
     rightid=@example.my.domain
     rightauth=pubkey
     rightsubnet=0.0.0.0/0
     leftsourceip=%config
     leftid=username
     leftauth=eap-mschapv2
     eap_identity=%identity


connection got setup ok, but no dns is installed on client's side. also
tried with  windows client, with same result

is it radius overriding rightdns setting?  i do not put anything but
authentication into radius yet. may it be the  reason?

thank you
