A Virtual Server is defined as service port. All requests to this port of your external IP address are forwarded to a certain internal IP address, e.g. requests via FTP oder POP3.
Use the Virtual Server to forward hack attacks via HTTP to your HTTP server in the DMZ.
You want to set up one FTP server, one Web server and an VPN server for your LAN.
Add 3 new rules:
Name of rule | Protocol | Start Port | End Port | IP Address |
---|---|---|---|---|
FTP server | TCP | 21 | 21 | 192.168.0.5 |
Web server | TCP | 80 | 80 | 192.168.0.6 |
VPN server | TCP | 1723 | 1723 | 192.168.0.7 |
Link the IP addresses (see last column) with the new rules accordingly.
