-===== How to Port Forward with Advanced Settings ===== 
- 
-It is never a good idea to add your node in DMZ. That will stop all the DPI and SPI and if you have the API enabled and white listed, you are putting your computer at risk! DMZ bypasses the SPI mechanism of the built in filters and all the internet traffic can reach your node directly. SPI (stateful packet inspection) firewall protects you by examining incoming packets against existing connections. 
-Also add UPnP text. If a router has it then it must be enabled. UPnP or NAT-pmp opens dynamic port ranges to act as an assist for SPI. Enabling NAT/UPnP solves problem for the most but unfortunately due to the torrent p2p laws most ISPs now filter ports by default at the client side so port forward is also needed. For example: 
- 
-219.88.183.49:12392 (qortal-1.2.3-2df0453), height 42318, sig: PXNoJM7W, ts 2020-07-31 17:17:24 
- 
-192.168.100.83:44380 (qortal-1.2.3-2df0453), height 42318, sig: PXNoJM7W, ts 2020-07-31 17:17:24

-Look at the second IP address with a dynamic port. This is UPnP working. Instead of 12392 , it has opened a 44380 port for TCP handshake / connect / ACK.
