I've had my servers on FIOS for many years, first using the Actiontec they gave me and recently we switched to bypassing the Actiontec and connecting our own router to the ethernet port on the ONT, Both setups work fine. the basics are the same in both cases.
As always, if you can't see a response from canyouseeme.org for the port used for Subsonic, you won't connect.
If the hostmachine can connect by using
http://localhost:SubsonicPort but you can't connect from other PC's insdie your home network, then you have a firewall on the hostmachine that's blocking the connection. If the local network can connect, then it's a port forward not properly set at the router.
HTH
