Transparent Proxy
F-Secure Internet Gatekeeper for Linux can work as a transparent proxy for each service (HTTP, FTP,
SMTP, POP). In this way, you can perform virus scans for services without having to change settings
for each user.
The following table displays which settings you need to change for the product to work as a
transparent proxy. The settings apply when the host name of the mail server is assigned to the host
name of Internet Gatekeeper (through proxy and DNS settings).
