Cisco Anyconnect Idle-timeout not working due to dns server configured

[jhettraven]

Can you help on this issue, 

DNS server is configured on the Cisco anyconnect VPN profile, making the DTLS tunnel not idle and idle to left timer is resetting. 

Any work around or solution for this to make the VPN tunnel disconnect due to idle timeout.

I dont know what relate of dns with idle except that anyconnect use GW for dns and this make vpn always not idle.

You can use split dns

Hi, the dns configured on this profile is the local dns not a public dns. That is why I think vpn idle timeout is not working, as the dns queries will still go to the tunnel
