If you add many addresses for split tunneling, Edge Client cannot establish a tunnel connection. The limits for these addresses are:
- Windows max limit is 20 KB (each Network Access property)
- macOS max limit is 64 KB (all Network Access properties)
- Linux max limit is 64 KB (all Network Access properties)
- Mobile clients (Android, iOS, Chrome) do not have a limit but may vary based on the platforms' support
- For theDNS Address Space, type the domain name in the formsite.example.com,*.example.com, or*example.comand clickAdd. To pass all DNS requests to the internal DNS server, specify*. If you do not specify a DNS address space or *, DNS does not work over split tunnels on Windows, macOS, Linux, or iOS. To pass all DNS requests to the internal DNS server, specify *. VPNs on Android devices do not support split tunneling.Wildcard matching occurs as follows:
For DNS Address Space to work properly on a Windows-based system, the DNS Relay Proxy service must be installed and running on the client.
- site.example.commatches only site.example.com. On macOS,site.example.comalso matches<prefix>.site.example.com, for example, a.site.example.com.
- example.commatches only example.com.
- *.example.commatches all<prefix>.example.com addresses, including site.example.com, example.site.example.com, and www.example.com. However, it does not match example.com with no prefix.
- *example.commatches example.com,<prefix>example.com (for example, dnsexample.com) and all<prefix>.example.com addresses, including site.example.com, example.site.example.com, and www.example.com.
