I have been contacted by our wells fargo bank rep and they told us a URL has changed and we are to add it to our firewall rules for continued access.  I have a SonicWall applianace, so the first question I have is where can I find the model number?  The interface recently changed and I used to be able to find it quickly.  Second question, how to I add this url to the firewall so it does not get blocked?

Unless you're actively blocking URLs on your SonicWall, you almost certainly don't need to whitelist this on in particular.  Have you tried to access the URL in question?  Are you unable to?

Also, HOW were you contacted by your bank rep?  Via e-mail?  Have you spoken to this person on the phone?  Are you sure you're not the victim of a phishing scam?

I spoke with the rep.  I can access it right now.  I just know that they are switching over to this permanently on Jan 24 of 2020 so they said to make sure it is in the firewall rules.  Maybe I am ok.

Unless your router blocks access to some component they need to run their web site, I can't imagine it being a problem.  

Can you find out what the change entails, and why they think you may need to configure your router because of it?  That would help.

Worry about it if and when it fails, when you can see actual evidence of the problem in the logs suggesting how to resolve the issue.

The whole point is to worry about it NOW before it fails.   No harm in preparation even if that prepartion may or may not fix the issue.  Is it a big deal to add this URL to a whitelist just to make sure?

Personally I wouldn't trust Wells Fargo as far as I could throw them, but any time someone suggests I should lower my defenses specifically to accommodate them I have to pause.   What are they doing that's so non-standard that it should affect my security footing, and how does that benefit me?  

I'm not saying I wouldn't, I would just really, really want to understand why.

You should only whitelist https://wellsfargo.com/* not any other URLs mentioned to you on a phone call, as they're likely scams.

Sorry.  Marked as solution before asking how to do this in Sonicwall and where to find my sonicwall model number so EE can walk me through

I've flagged the question so a moderator can remove the "solved" for you.

Is the model number not on the back/bottom of the unit?  If you log in to the firewall, does it not tell you the model there?

If you're able to log into the Sonicwall, you should be able to find the model information there. Go to Monitor > System Status.

But as pointed out before, you only need to look at whitelisting if you have a proxy or web filter of some sort. Sonicwalls do offer web filtering, but I've seen this more often not utilized. And even then, in most cases, whitelisting isn't necessary even though vendors always like to say that you should do so. It's amazing how many vendors I've pushed back on because in making the choice not to whitelist, I found that there are actually problems with their systems that they choose not to correct.
