Ports are still switched. You need to use the high number ports on the WAN IP translated to the 80/8887 ports on the Tablo IP.
Agreed with above, for example the first entry should read DEST PORT/IP as “192.168.1.10:8887”.
The “internal” port of destination port is 8887. You are forwarding external port 21917 to internal port 8887.
Something else is going on with my scenario. I believe I have a double NAT with my fiber gateway and UDM-Pro. Thanks for the input.
Search the forums for double NAT, some helpful posts and links about putting your ISP modem in bridge mode. Port forwarding will not work in double NAT.
