Choosing the right VPN for your Roadwarrior/Home-to-Office setup
When it comes to remote VPN access, there are three major VPN types supported by Zyxel to choose from:
- IPSec VPN (IKEv1/IKEv2)
- L2TP over IPSec VPN (IKEv1)
- SSL VPN
All of these vpn types have different security levels and advantages:
- L2TP over IPSec VPN mostly is not as secure as the IPSec Client (but still secure for bigger companies to fully rely on, so do not worry), but is supported by nearly all client platforms without additional client software and/or license needed
- SSL VPN is more flexible than the others due to using the standard HTTPS port (avoiding potentially blocked ports by local internet service provider)
- IPSec VPN offers a more sophisticated setup in terms of security settings (but may require a software client installation depending on IKE type and ciphers used)
You may have already received guidelines/instructions from your employer or client, which VPN type is to be used or established. The guidelines below shall help you in finding the setting up the right product for your needs and help you with upcoming challenges!
Let's use this opportunity to make your home-office-setup a true success story!
SSL VPN (via SecuExtender software client)
SSL VPN is a VPN setup which uses Zyxel's SecuExtender software. It's major benefit is that it runs via SSL/TLS protocol, so its first of all very secure. Another benefit is, that the standard HTTPS port rarely is blocked in any kind of setup, because this is the port used for normal VPN, meaning that it is very flexible in avoiding blocked ports. It's capability to be combined with an Active Directory user-database makes it a staple in the VPN setups.
Note: SSL VPN is limited to Windows and macOS running SecuExtender client software.

L2TP over IPSec VPN
L2TP VPN at its core is quite an old standard, but still remains a legit option for big VPN setups these days. Using a technology which combines L2TP over the IPSec VPN standard, it is ultra-flexible platform wise, since all common platforms offer integrated L2TP-client software/drivers. Also, L2TP over IPSec VPN can be easily linked to an Active Directory, which makes it especially useful for big company setups.

IPSec VPN
IPSec VPN is the old standard when it comes to flexibility in encryption of the VPN Tunnel - at least when using proper client software. IPSec VPN using the ZyWall IPSec VPN Client is very flexible in setting up encryption algorithms and can provide the perfect compromise between payload and security that you need for your network. Unlike L2TP over IPSec VPN, IPSec VPN by default does not push all client traffic through the VPN tunnel, which is great if you seek to access business-related resources, but do not want to load your VPN Tunnel with the client related traffic toward the internet.
