Boot, access, network and performance problems, and hardening.
- Boot — On some serial connected devices the console settings are different, in which case you would not be able to start the installer.
- Web interface access — If for some reason the webgui certificate is broken, you can reconfigure access using the console menu. Select Set interface IP address (option 2)…

- OpenVPN — While not strictly necessary, it is possible to assign individual interfaces for OpenVPN servers and clients alike. However doing so may yield…
- Performance — RSS is used to distribute packets over CPU cores using a hashing function – either with support in the hardware which offloads the hashing for you,…
- System hardening vs performance — Ixolate tends to choose more strict hardening options by default, so when comparing performance between upstream standard FreeBSD it’s good to know…
