A Citrix Secure Gateway Server is an Internet gateway server that secures communications between ICA Client and MetaFrame servers. In Normal mode, no configuration on the client is required. If your Citrix Secure Gateway server is running in Relay mode, you will need to specify the details in the client. If you are not sure if there is Citrix Secure Gateway on your network, or you are not sure what mode it is running in, contact your Citrix administrator.
