3 PC's at home through Linksys router (1 wired, 2 wireless). I can get Remote Assistance (RA) and Remote desktop to work fine inside my network, however unable outside. I've opened port 3389. I've even tried going direct through the modem at both ends (no router). Error on my end as Expert - "Remote desktop connection disconnected. Please try again." Error on other end as Expert "Could not resolve host name." Running out of ideas.
