Help > IT Topics > Firewall Rules to Run RMS

The following firewall rules are required to ensure the correct running of RMS:

1.DHCP UDP

a.RMS device source port 67 to 255.255.255.255/32 destination port 68.

b.DHCP server source port 67 to RMS device destination port 68.

c.RMS device source port 68 to DHCP server destination port 67.

2.Modbus UDP

a.RMS device source port dynamic to 255.255.255.255/32 destination port 502.

b.RMS device source port 502 to 255.255.255.255/32 destination port dynamic.

3.Modbus TCP

a.RMS device source port dynamic to other RMS devices destination port 502.

b.RMS device source port 502 to other RMS devices destination port dynamic (this is routable traffic. So, if the RMS device/RMS config exists in another LAN you can connect to a device via IP address).

4.HTTP TCP

a.RMS device source port dynamic to a device with a web browser destination port 80.

b.RMS device source port 80 to a device with a web browser destination port dynamic (this is routable traffic. So, if the device with a web browser is in another LAN you can connect to it).

c.RMS device source port dynamic to 156.67.38.83/32 destination port 80.

d.RMS device source port 80 to 156.67.38.83/32 destination port dynamic.

5.DNS TCP/UDP

a.RMS device source port any to DNS server port 53.
