I'm using the Linksys BEFW11S4 with the latest firmware (i upgraded it
yesterday). I know what no-ip.com can do for me but I am reluctant to do
that because my IP has remained static thoughout this entire experiment to
get RDC to work. When I go to whatismyip.com or run ipconfig, the public IP
shown is 24.44.xxx.xx. I assume this is for the router.

I agree that it's unlikely that 3389 is being blocked outbound from verizon
dsl and our cable modem though maybe on the T3. If that is the case, could
it be anything else besides my router settings? Is there anything else I
could be missing there?

Thanks,
Jason
