Installing and Configuring the SteelHead
This chapter describes how to install and configure the SteelHead in an in-path and out-of-path network
deployment.
Read and follow the safety guidelines described in the Safety and Compliance Guide . Failure to follow
these safety guidelines can result in damage to the equipment.
Choosing a network deployment
Typically, you deploy the SteelHead on a LAN, with communication between appliances taking place
over a private WAN or VPN. Because optimization between SteelHeads typically takes place over a secure
WAN, you don’t need to configure company firewalls to support SteelHead-specific ports.
Note: If there are one or more firewalls between two SteelHeads, ports 7800 and 7810 must be passed through
firewall devices located between the pair of SteelHeads. Also, SYN and SYN/ACK packets with the TCP option 76
must be passed through firewalls for autodiscovery to function properly.
For optimal performance, you should minimize latency between SteelHeads and their respective clients
and servers. SteelHeads should be as close as possible to your network endpoints (client-side SteelHeads
should be as close to your clients as possible and server-side SteelHeads should be as close to your
servers as possible).
Ideally, SteelHeads optimize only traffic that is initiated or terminated at their local site. The best and
easiest way to achieve this is to deploy the SteelHeads where the LAN connects to the WAN, and not
where any LAN-to-LAN or WAN-to-WAN traffic can pass through (or be redirected to) the SteelHead.
