RR uses the port 7773 for all communication to the rrServer.

If you have a firewall, please open the port on the rrServer.

If you have a personal firewall that blocks outgoing connections (the Windows firewall does not), then you have to open the port on all machines as well.



Windows



The rrWorkstationInstaller adds a firewall rule for you.


If you do NOT want to use the rrWorkstationInstaller and manually configure your firewall, then please follow these steps:

  1. Open the windows Firewall settings: Control Panel\All Control Panel Items\Windows Firewall
  2. Choose "Advanced Settings" from the left menu
  3. Click on "Inbound Rules"
  4. Right Menu "New Rule..."
  5. Choose "Port", Next>
  6. Choose TCP and set "Specific local Ports: 7773", Next>
  7. Allow the connection, Next>
  8. No change (everything checked), Next>
  9. Name it RoyalRender, Finish.





CentOS 7+ / Linux with firewalld



  1. This enables it for the current session:
    Open a terminal and execute
    firewall-cmd --zone=public --add-port=7773/tcp

  2. This  saves the setting that it works after a reboot:
    Open a terminal and execute
    firewall-cmd --zone=public --add-port=7773/tcp --permanent



CentOS 6 / Linux with iptables




  1. open a terminal and execute
     iptables -L.
    It should look similar to this output:
    Chain INPUT (policy ACCEPT)
    target     prot opt source               destination         
    ACCEPT     all  --  anywhere             anywhere            state RELATED,ESTABLISHED 
    ACCEPT     icmp --  anywhere             anywhere            
    ACCEPT     all  --  anywhere             anywhere            
    ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:ssh 
    REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited 

    Chain FORWARD (policy ACCEPT)
    target     prot opt source               destination         
    REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited 


    Chain OUTPUT (policy ACCEPT)
    target     prot opt source               destination        

  2. Take a look at the first section "Chain INPUT".  You have to add a line before the 5th line "REJECT". This will shift REJECT to line 6.
    To add the rule to the 5th line, execute this commandline:
    iptables -I INPUT 5  -p tcp --dport 7773 -m state --state NEW,ESTABLISHED -j ACCEPT


  1. Execute
    /sbin/service iptables save
