Frequently Asked Questions
Does VPN Tracker support legacy algorithms required by macOS Server VPN
Yes. VPN Tracker includes support for legacy encryption and authentication algorithms such as 3DES, DES, SHA1, and older Diffie Hellman groups that are required by macOS Server VPN.
These algorithms are no longer supported by the built in VPN client in macOS 26, which leads to macOS Server VPN not working errors. VPN Tracker maintains compatibility so you can continue using your existing macOS Server VPN setup.
