<div>On a strongswan client configuration, when for example (in /etc/ipsec.conf) leftdns=%config4,%config4 and on the server there are in the configuration: rightdns=100.100.5.2,100.120.5.2,fec0::1,fec0::2 (2 IPv4 and 2 IPv6 addresses), I expect receiving only
the 2 IPv4 addresses in environment variables PLUTO_DNS4_1 and PLUTO_DNS4_2. But, I also received PLUTO_DNS6_1 and PLUTO_DNS6_2 with the 2 IPv6 addresses. </div>
<div> </div>
<div>Moreover, if leftdns parameter is not defined in /etc/ipsec.conf on client side, the environment variables PLUTO_DNS4_1, PLUTO_DNS4_2, PLUTO_DNS6_1 and PLUTO_DNS6_2 are likewise set with DNS IP addresses from the server.</div>
<div> </div>
<div>My question is: What is the aim of setting the parameter "leftdns" with %config4 or %config6, if the server or local strongswan does not take into account ?</div>
