nighthawk cax80

[smb916]

I purchased a Nighthawk CAX80 Router/Modem.  I connected it and it was allowing me access to the internet.  When I began to work from home, it will not allow me to access my work server through sonic wall.  For two months  I have been requesting support help and no one can seem to help.  Does anyone have any suggestions before I throw $400 out the window?

So internet wise, it works?

Its just trying to access one thing from a server at your job? 

Have you tried a different dns? like googles at 8.8.8.8 or 8.8.4.4  or cloudfare at 1.1.1.1

Are you able to access your work server at different locations (not your home)?

What error are you getting?

would be good to post a setup diagram and where sonic wall is kept

Hard to comment without much details. 

if you have firewall on the LAN, it most likely will require to be put on DMZ or specific port fowards.
