I have a Sonicwall TZ 170.  Things are working fine but it would appear that it is somehow blocking access to a few select sites.  Mostly Webmail type sites.  Hotmail,gmail, yahoo mail.  I get to the login screen enter my password and it just sits there.  If i bypass the firewall and plug directly into the net everything works fine.  Not exactly sure why or how this is happening?  Any ideas?

Since you have had no replies....
I have seen several items in different message boards that lowering the MTU value in this situation, has resolved. Doubtful but you could try on the router lowering to 1320 as a test. If that resolves, gradually increase it to 1500 (1492 if PPPoE connection with your ISP) untill it "breaks".

I found the solution to my problem:

It was a firware revision specific issue w/ HTTP host tag enforcement related to the CFS on the TZ170 -

Log in to the firewall https://firewallip/diag.html,
go to  Internal Settings.
Scoll down to a checkbox labelled Enforce Host Tag Search with for CFS
uncheck it
scroll up and hit Apply
Then Close button on the bottom left.

Not sure what this is or what it does but I found it and it worked.
