Firewall

Parent Previous Next


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


3.Execute
/sbin/service iptables save
