-Routes to local DNS that get added due to 'allow local DNS' option in Network Access config do not get removed once network changes after VPN is established.
If the BIG-IP administrator changes the network after a VPN is connected, and if DNS servers have changed, then routes to old DNS servers (which may or may not be reachable) will be left in the routing table.
- 'Allow local DNS' option is selected in Network Access config. - BIG-IP administrator changes the network configuration after VPN is connected.
None.
In Network Access, routes added by 'Allow local DNS servers' are now removed when they are no longer among a client's local DNS servers if the client's network properties change.
