I had an old Linksys wired router that was acting the same way. I was able
to access all sites I tried, but one (the web site was was actively working
on) I could access from a direct connect to the modem, but not from the
router. I had Cox reset my modem, I even had them reprovision me and assign
a new IP but nothing worked (hmmm now that I think about it, the reprovision
MAY have worked for a couple times, don;t remember). On the router side I
reflashed the firmware, and moved the ports I was using. I even reloaded my
network drivers on the PC. I eventually got a new router and all was well
again. the funny thing was I could access the other domain on hte same host
(used bluehost.com with several domains attached)
I do not remember if I could connect using the IP, may not have even tried.
