SecuExtender SSLVPN can't connect

Zyxel_Kevin

Symptom:

1)SSLVPN can not connect on Windows SecuExtender clients, but always can connect on MacOS clients.

2)You have Destinat NAT to SSL Port on upper device, which means the port have been translated, For example.

Firewall_IP:50000 → Firewall_IP:10443 (SSLVPN Port)

Workadound:

Since requst from windows SecuExtender client contain the port information, it will cause some daemon can't be called correctly when there DNAT existed.

Please remove the DNAT. For example

Firewall_IP:10443 → Firewall_IP:10443 (SSLVPN Port)
