DNS Relay Proxy service not working with Dialup Entry / Windows Logon Integration

Hello,

I am trying to establish DNS Relay Proxy service working when users connects to VPN from the Microsoft login screen. I was following the https://support.f5.com/csp/article/K07608215 instructions. When testing I noticed that DNS Relay Proxy service only works if user is conneted through BIG-IP Edge client, while it does not work for users who login through dialup entry.

I wish to use it to resolve some DNS names differently for users that are on the VPN and use the same central DNS servers as internal users in LAN network.

Thanks in advance

Sandi
