1/21 January 21 DNS PreCheck Beta for Windows Roaming Client

DNS PreCheck

is now generally available in the

Windows 3.1.0 Beta Roaming Client

for customers using the Beta Channel.

To enable DNS PreCheck, go to

Roaming Clients → Control Center → Connection & Filtering

in your dashboard.

✨ What’s New

DNS PreCheck (modern DNS protection)

– A transparent DNS proxy that validates and filters DNS locally before queries leave the device. This reduces conflicts, improves reliability on unmanaged networks, and helps preserve connectivity without requiring DNS setting changes.

New Connection & Filtering Mode framework

– Configure behavior directly from the

Roaming Client Control Center

across three dimensions:

Connection Mode:
Transparent Proxy or DNS Loopback
Filtering Mode:
Classic DNS or DNS PreCheck
Failover Mode:
Fail Open or Fail Closed

✅ Why It Matters

More reliable protection
on untrusted networks with fewer DNS conflicts
Greater admin control
with predictable behavior and clearer outcomes
A stronger foundation
for future feature delivery and cross-platform consistency

⚠️ Known Limitations

Some network and VPN/security configurations may impact behavior in certain environments. For details, see our knowledge base.
