I recently got a DSL line and decided to add a router for
firewall/security.
I have a Westell 6100 DSL modem and now a Linksys BEFSX41 router.

The problem I am having is that I can't access certian webpages that I
need to access. Specifically I can't access windows update and Most
online banking pages. I can access some secure "https" site but
others I can't reach at all.
Most web pages load fine.

I have googled search strings for hours and can't find anything that
helps.

Does anybody know what the problem is? How does one go about
troubleshooting this sort of problem?

Thanks

Are you sure the 6100 is operating in "modem" or "bridge" mode instead of
router mode, which is probably default.
You can tell by where you enter the username/passwd. If it is in the 6100,
it is router, and you are doing double NATing.
If in the Linksys you are setup properly, and should be OK. How did you
setup the Linksys - just default out of the box? Then it is probab running
DHCP to the 6100 and you are double NAting.
See this page for some help.

Additionally, If I connect directly to the DSL modem everything works fine.
It's just when I hook up the router that I loose connection to some websites.

So I setup the modem to work in bridge mode and disabled dhcp but I
am still having problems. Windows update gets all the way to the
download step and hangs there. I can get to my online banking through
quicken but not through the secure webpage.

The FAQ page from the previous post was helpful but the web interface
of my modem is very different from the one listed there and I can't be
sure if I got everything the same.
