It's a small problem because I don't have an immediate need to get into the
router other than to confirm settings. It would be a big problem if I need
to change them.

Compatible: I can plug it into the local network and it will be on the same
subnet and its static IP address would not conflict with any existing IP
addresses (dynamic or static). I don't know the router's IP address doesn't
conflict but I suspect it doesn't -- I can't get to it at its default IP
address which implies it has been changed. If someone changed it then I
would hope they changed it to an open (as in outside the range given the
DHCP to dish out and not given any other comptuer) IP address. Without
knowing what it was given, I can't get to it. As somepoint, I will connect
to it and check it out.

Since I wrote my original post, I have connected a cable from the web
router to the switch for the rest of the network -- I could then ping the
web server from the rest of our network. Yeah! I then put the SonicWall in
that line. I could no longer ping the web server. Awww!

Also, since I wrote my original post, I found that my SonicWall is not the
model I thought it was. This one does not have a DMZ port. The router has
4 ports on it so I expect I can just connect the Wan port to the router and
the LAN port to the switch. But it doesn't work.
