The Host can be configured to report to one or more RAS Servers. The Gateways subsection includes settings for each RAS Server this Host should report to. The Account User can click on the Edit button to view and/or edit the configuration options for each RAS Server.
Below is a table of the fields, values and actions available on the RAS Servers popup window:
Field
Description
Connection restrictions
Ensure that Master services and/or administrative services to this Host can come only through a RAS Server listed below (i.e. no peer-to-peer)
Remote control and related services
Ensure that remote support and collaboration services, including Input Control, File Transfer, Remote Printing and Chat, can only come from a listed RAS Server (i.e. Master connections and services requested on a peer-to-peer basis will be rejected)
Host administration and remote management
Ensure that administrative services, including Host Administration and Remote Management, can only come from a listed RAS Server (i.e. not valid for peer-to-peer)
Add Gateway
Click on this button to add an entry to the list of RAS Servers with which this Host is allowed to communicate; see the Gateway Connection Properties popup window below for more details
Resend Status
Click on this button to cause the Host to recheck the status of its Gateway connections with all the listed RAS Servers; the status icon in the first column of the table entries below will be updated to reflect the updated status
Gateway Details
Each entry in the RAS Server list will have the following fields and values:
Status
The status of the RAS connection between the Host and the listed Gateway Server will be indicated by one of the following status icons:
Cube with green dot
Status OK, relationship to RAS Server is OK, Reverse connection established
Cube with yellow dot
Status OK, relationship to RAS Server is OK
Question mark
Status unknown, possibly waiting for ‘Resend’
Shield with X inside
SSL certificate error; select entry and click ‘View Error’ for more information
Error triangle with ! inside
Error condition; see error code for more information
Station Specifier
The DNS name, RAS Server name or network IP address for the listed RAS Server
Protocol
The network protocol being used for communication between the Host and the listed RAS Server; can be UDP/IP, TCP/IP, SSL, Web Sockets (WS) or Secure Web Sockets (WSS)
Address
The IP address of the listed RAS Server; can be IPv4 or IPv6 format
Last Status
The last status of the RAS connection between the Host and the listed Gateway Server, in internal format (for debug purposes)
Actions
Following is a list of actions that can be taken to modify the list of RAS Servers (the Host checks status in order)
Edit
View/edit the configuration settings for the RAS connection with the listed Gateway Server
Delete
Delete this entry from list of RAS Servers with which this Host should communicate

When the Add Gateway Server button is clicked, the Gateway Connection Properties popup window appears:
Below is a table of the fields, values and actions available on the Gateway Connection Properties popup window:
Field
Description
Gateway Server
Specify details about the new Gateway Server
Protocol
Choose the network protocol that should be used to communicate with the new Gateway Server; options include UDP/IP, TCP/IP, SSL, Web Sockets (WS) or Secure Web Sockets (WSS)
Port
Specify a port number for the protocol selected above; or specify Standard to use default port number (default port number for UDP and TCP and WS is 2303; default port number for SSL and WSS is 443)
Station Specifier
Type in the DNS name, Gateway Server name or network IP address for the new Gateway Server
Reverse connection mode
Specify whether or not the Host should use a Reverse connection to communicate with the RAS Server. With Reverse connection, the RAS Server will be able to access the Host through firewalls and Net Address Translation (NAT) devices. The potential downside is that each Reverse connection requires some overhead to be established and maintained; the RAS Server may have limited resources to support large number of concurrent Reverse connections (Default = Automatically determine if Reverse connection is necessary, max 2,000)
Never keep a Reverse connection to this RAS server
Select this option when the Host and RAS Server are on the same LAN and the RAS Server can easily establish a Master connection to the Host
Always keep a Reverse connection to this RAS server
Select this option when the Host is not easily accessible by the RAS Server, e.g. is behind a firewall and/or router with a NAT table. The Host will always use a Reverse connection to maintain communication with the RAS Server.
Automatically determine if Reverse connection is necessary
Select this option to cause the Host to figure out if it needs a Reverse connection to communicate with the RAS Server based upon its IP address.
View certificate
Click on this option to view the SSL certificate for this Gateway Server. See RAS Server Installation > SSL certificates section in the PC-Duo RAS Server Guide for more details.
NOTE:This command only appears when SSL-related protocols are selected (SSL, WSS).
