Adding Port Forwarding Rules
The HTTPS traffic (TCP port 443) from external clients will be forwarded to the UNMS server.
Follow the steps below to add the Port Forwarding rules to the EdgeRouter:
1. Select the WAN and LAN interfaces that will be used for Port Forwarding. The auto-firewall feature will automatically open the required ports in the firewall.
Firewall / NAT > Port Forwarding
- Check: Show advanced options
- Check: Enable auto firewall
- Check: Enable Hairpin NAT
WAN interface: eth0
LAN interface: eth1
2. Add the port-forwarding rules for TCP ports 443.
Original port: 443
Forward-to address: 192.168.1.10
Forward-to port: 443
3. Apply the changes.
The above configuration can also be set using the CLI:
set port-forward auto-firewall enable
set port-forward hairpin-nat enable
set port-forward wan-interface eth0
set port-forward lan-interface eth1
set port-forward rule 1 description https
set port-forward rule 1 forward-to address 192.168.1.10
set port-forward rule 1 forward-to port 443
set port-forward rule 1 original-port 443
