How can I resolve constant RDP session disconnections on Zyxel USG Flex 100?
If your RDP sessions are constantly disconnecting when using a Zyxel USG Flex 100 firewall but work fine when connected directly to a modem or a wireless hotspot, the issue could be related to the ICSA protection mechanism on the firewall.
To resolve this, follow these steps:
- Access the device's command-line interface (CLI).
- Type the following commands:
Router# configure terminal Router(config)# firewall icsa icmp-destroy-session disable
Disabling the ICSA destroy-session feature has been known to work and prevents the RDP session interruptions.
