USG FLEX series and SSL VPN compatibility

MarkoD

Hi,

Does the USG FLEX (non-H) series support SSL VPN with the latest firmware? I know the client has been discontinued, but I would like to know whether these firewalls still support it?

The specs do not mention SSL VPN anywhere, however the manuals do have a chapter dedicated to SSL VPN configuration.

If yes, can someone post the maximum concurrent SSL VPN connections for each USG FLEX model?

Hi @MarkoD ,

The SecuExtender SSL VPN macOS and Windows clients have reached end of life (EOL). However, if you have a valid license, you can still use the software, and USG FLEX continues to support it.

You can download the software using the links below:

• [macOS SecuExtender SSL VPN client 1.2.6]
• [Windows SecuExtender SSL VPN client 4.0.5.0]

Regarding to the maximum concurrent SSL VPN connections for each USG FLEX model, you can refer to User guide page 1231 > APPENDIX B Product Features:
