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

for more information on setup requirements for these 

scenarios.

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.
