HTTP Tunneling
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:
za serial-to-serial HTTP tunnel connection
za serial-to-host HTTP tunnel connection
za host-to-host HTTP tunnel connection
zTunnel 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.
