can i run a full node on a laptop without a 3rd party router? i am  using verizon fios and have attemped to connect to full node. verizon said that i can n0t do it on their router and would need to purchase a 3rd party router and daisy chain to theirs. Any suggestions would be appreciated. thanks.
This may be a good start.

There may be more specific info about configuring a Verizon router on their website.

There are services that allow routing to your node and I believe Verizon routers support using dyn.com and other DNS services - it may be in an advanced configuration tab in the router UI.

It depends on what you are trying to do - but this should point you in the right direction.
