But as I said, I would recommend a setting up a DMZ instead as your node will see all incoming connections coming from your routers LAN IP address.
What about WAN<->DMZ/Firewall<-port-forward->bitcoind/lnd server ?
Don't seem to have any issues with the Bitcorn node so far.
I did make sure to add the --ipaddr with my WAN IP. Not showing up on any maps yet tho

Figured I've done something wrong.
