Thanks for your feedback. To answer your question first
please note I already mentioned "all works well", meaning
there are no other problems.
Since I am specifying the modems IP there is no need for DNS as
I understand it. Aside, I have no problems reaching anything on
the WAN using verbose URL's
My best WAG is either the router is blocking
the modems non routable IP address or the modem's firmware
is buggy. However the router is set to DMZ and should not
be blocking anything and the modem has been on the market
for two years and has the latest firmware update from a year
ago.
Perhaps its possible the ISP has reprovisioned the modem
online to stop access to its configuration, logs etc but they say no.
Another thought is that the software firewall is blocking
access, but why that IP (192.168.100.1) and not the IP
of the router (192.168.123.254) which I CAN reach without
problems??
As Mulder would say, "the truth is out there" :-)
TIA,
Tony
