Settings
1 Install an SSH server to the same server (or a computer on the network) as F-Secure Linux
Internet Gatekeeper.
For certain Linux distributions (such as Red Hat 7 and later versions), openssh is installed by default.
2 Install a SSH client to the client computer that accesses the SSH server.
3 Change the port forwarding setting of the SSH client so that Internet Gatekeeper becomes the
localhost destination.
Set the Config file in the following way. In the example below, the SSH server host is
"ssh-server", the SSH user name is "ssh-username", and the Internet Gatekeeper host is
"fsigk".
Host ssh-server
User ssh-username
LocalForward 25 virus-gw:25
LocalForward 110 virus-gw:110
LocalForward 9080 virus-gw:9080
4 Connect the SSH client to the SSH server.

Web browser's proxy : http://localhost:9080/
