1)In router configure Trigger port 443:443 and Target port 5001:5001 |
By default Port triggering will be disabled in the RPI .We can enable using two methods .One is through DM and other way is through UI

In Your client machine(LAN)you have to run : nc -u -l 2399
From external WAN machine run nc -u 192.168.2.30 2399, while client machine(LAN)run https service(In browser https://www.google.com)

WEB GUI:
Step 1: Login to webui, from navigation -> Advanced ->Port Triggering. Click on Add Port Trigger (Configure Trigger port as 443:443 and Target port as 5001:5001)
Step2: In Your client machine (LAN)you have to run: iperf -s -B 10.0.0.106 -i 1 -p 5001 (10.0.0.106 - LAN IP)
Step3: In the WAN machine run iperf -c 192.168.161.216 -p 5001 -i 1 -t 60 -B 192.168.160.173 (192.168.161.216 - router uplink ip address, 192.168.160.173 - WAN PC Ip) same time in the client machine (LAN)run https service (In browser https://www.google.com)
