I recently installed a SonicWall TZ270 Firewall in my home office environment.  I have four different "zones" set up.  The work zone has my main work PC, a Windows 2012 file server, a NAS device, and a network printer in it.  I am having several problems on start-up that I think are coming from my configuration and policy.

First, the work network is currently on the private network.  Ido have plans to move it off this default/common private network IP range.  When I try to log into my SonicWall device which is at 192.168.1.ABC I get multiple error messages.  I first get a message from BitDefender that the site is unsafe and I should go back.  It gives me the option of adding the site to an exception list.  Sorry, I cannot recreate the exact message.  When I say it is fine I get a further warning from Firefox or Chrome.  The Firefox warning:

Firefox detected a potential security threat and did not continue to 192.168.1.ABC. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

The Chrome warning says:

Your connection is not private
Attackers might be trying to steal your information from (for example, passwords, messages, or credit cards). Learn more

Originally, based on a training video SonicWall posted about setup, I set up policies allowing only certain traffic from "Work" to WAN.  I was only allowing DNS, HTTP, HTTPS, PING, and FTP.  A number of services did not work (email, remote access to a network via Citrix) so I eventually added a policy that allows ALL traffic from "Work" to WAN.  My plan is to address this in a separate question. 

1. Based on my firewall and its configuration, is there any risk in my going to this private address?  I assume not, but want to confirm.  I can always access the TZ270 using a laptop that is not in my Work network.

2. How do I stop this message from coming up every time I go to the site?  Is there a problem with the certificate on the firewall?  I would prefer to fix the problem as opposed to adding an exception, but an exception is OK if that is the best way to fix it and is safe.
