Firewall
This “Firewall” page allows you to configure ICA connections through a firewall or a SOCKS proxy server. (Firewalls and SOCKS proxy servers are used on networks to improve security.)
Use Alternate Address
If you are using ICA sessions to connect to a specific Citrix server behind a firewall, you have to activate this option. The Citrix server (usually) has a different IP in the local network than from the outside world. (For details on server configuration, look up the “altaddr” command in your Metaframe admin manual.)
After enabling the alternate address, add the server in the “Address List” in the “Server Location” box of the “Global ICA Settings”
Connect via SOCKS or Secure Proxy Server
You can configure the ICA sessions to connect to a Citrix server through a SOCKS proxy server or a Citrix Secure Gateway (in relay mode).
To make the "Secure Gateway" field accessible, the "Browser Protocol" in the "Server Location" tab has to be set to "SSL/TLS + HTTPS"
Auto Reconnect
