  • One option might be to have your router map an inbound WAN port # to another LAN port #. My Linksys WRT160Nv3 has this option.

    You would need to figure out what ports you need and what ports your ISP does not block.

  • Which is it? All or some?  If it's just port 80 then you still can get through on https  (port 443)

  • Turns out to be all.  I don't know if they are actively blocking all unused ports or if I'm sitting behind some NAT device.

    OBTW: I'm way out of my depth on this stuff; learning with every message.  Thanks for the reply.

  • Do you run a cable modem from cox and then a second router?  If so you need to look up how to put your Cable Modem into bridge mode.  Effectively you are behind two NATs and this would give the impression that all ports are blocked.

    However from this post I think you may find only port 80 is blocked, cox seem to allow traffic on 443 and 4125:

    Though maybe you are on a different package.  Where are you getting your info that cox blocks all ports?

    Cheers,
