Hello everyone.
I’m still a little new here and to Monero but loving it! 
I’ve just read the Tutorial “How to run a Monero (XMR) node” on Monero.com.
However I am not familiar with Ubuntu and have only used the Monero GUI Wallet with local node selected.
I was hoping to get some more information on how I could possibly set-up my Windows PC desktop node to be open so that I could use it to sync my phone.
If you have any links or personal advice that may assist I’d really appreciate it. Thanks.
add
--rpc-restriced-bind-ip=0.0.0.0 --rpc-restricted-bind-port=18089
to startup flags
on router, Port forward 18089 from public ip to private ip of node (192.268 etc)
Example:
Enable port forwarding for 18089, like the pics here: GitHub - nahuhh/android-termux-monero-node: Run a Full Monero Node on Android through Termux
note: pics show 18080, but you will want to do 18089 (add 18080 if you want to enable incoming connections for blockchain sync)
The process for port forwarding may vary slightly depending on the router used. If you search “port forwarding” and add the name / brand of your router, you should find a guide.
I would set up your Monero mode as described here, but I wouldn’t port forward it in your router. I would install something like Tailscale or ZeroTier on both devices and use that to connect them without port forwarding instead.
Thanks for the reply. 
Lemme try this out and see how it goes. Thanks again.
Thanks for the reply. I’ll look into the recommendations you’ve mentioned. Thanks again.
