I need your help solving a problem(I think it's hard so I'm assigning it 500 points).
I went into a customer site, and found no firewall was in place. So, I installed a SonicWall PRO 3060, and correctly configured the appliance. I set all of the pc's up for DHCP and the servers I setup with a static IP address.
Unfortunately, now I cannot receive inbound emails. I can send email out, and can receive intracompany emails, but cannot receive emails outside of the office.
EEK PLEASE GIVE ME SOME POINTERS! =)
