Hello,
I have a question about using a DMZ and setting up Email, FTP and Web access. Before I get into it, I think I should explain our situation. We currently have a Linux based web/email/ftp server that has a firewall running on it. Unfortunately this box is outside the corporate HW firewall (exposed to the Internet). Our corporate firewall handles a DSL connection for Internet access and the web/email/ftp server handles a wireless Internet connection (static IP). We currently can access the web/email/ftp server remotely from intranet.companyname.com (web), mail.companyname.com (mail), ftp.companyname.com (ftp) or the static IP address. I recently got approved for a SonicWALL 2040 appliance that supports two WAN connections (both our wireless and DSL Internet connections). I like this because it centralizes the Internet connections and it has fault tolerance. I then want to put our web/email/ftp server in the DMZ of the SonicWALL appliance.
Question: Will users still be able to access the web/email/ftp server internally/externally from intranet.companyname.com (web), mail.companyname.com (mail), ftp.companyname.com (ftp) or the static IP address? If so, how does that work? If not, how do I grant them access?
Thanks
