REMOTE ACCESS HOW TO
Page 36 07.10.2021
5.6 Additional network settings (RAE only)
In some configurations it may be desired to provide remote access to controls connected to
the control running RAE.
•
To remotely access the other controls, it is required to setup port forwarding using
the firewall.
•
Firewall is supported on Salamander OS >= 09.03.141. Firewall commands are
described in the Lasal OS documentation.
1. Connect to the control via LASAL CLASS 2.
2. Open the Autoexec.lsl using Class 2: Debug > File Transfer > Edit Autoexec.lsl. Add
firewall commands to handle the forwarding and NAT to downstream devices.
a. Example: control with IP address 10.100.3.3 is connected to the control
running RAE with IP address of 192.168.111.20. The following lines must
be added to forward a VNC connection:
i.
FIREWALL “-A FORWARD -j ACCEPT -p tcp --dport 5900 --sport
5901 -d 10.100.3.3 -m state --
state”
ii.
FIREWALL “-t nat -A PREROUTING -p tcp --dport 5901 -j DNAT
--to-
destination 10.100.3.3:5900”
iii.
FIREWALL “-t nat -A POSTROUTING -j MASQUERADE”
3. Save the changes and reboot the control.
