HTTP Tunneling

Overview

A HTTP tunnel is a firewall-safe communication channel between two IOLAN’s. HTTP tunnels can

transport arbitrary TCP/IP or UDP/IP data for applications such as Telnet/SSH or any other TCP

application and most UDP applications.

You can configure the IOLAN for:

z a serial-to-serial HTTP tunnel connection

z a serial-to-host HTTP tunnel connection

z a host-to-host HTTP tunnel connection

z Tunnel Relay connection

See Configuring HTTP Tunnels for more information on setup requirements for these

scenarios.

Functionality

The information in this section applies only to setting up HTTP tunnels.

A minimum of two IOLAN’s must be configured to create a communication channel. One IOLAN

must be configured as the listener and the other IOLAN must be configured as the connecting

IOLAN.
