Barracuda SSL VPN Deployment
Standard Deployment
The standard deployment consists of the Barracuda SSL VPN receiving incoming connections on port 443 forwarded from the network firewall. This is the simplest configuration and sets up the Barracuda SSL VPN in minutes.
Deployment in the Demilitarized Zone
An alternative deployment option is placing the Barracuda SSL VPN in the demilitarized zone (DMZ). Deploying in the DMZ requires opening ports on the internal firewall to allow access to services via the Barracuda SSL VPN. An administrator need to open ports 80 or port 443 if it’s HTTPS to grant access to the intranet Web site, enabling the Barracuda SSL VPN to act as a secure proxy for the intranet.
