CHAPTER 24
Redirect Service
This chapter shows you how to configure HTTP and SMTP redirection on your Zyxel Device.
24.1 HTTP Redirect
HTTP redirect forwards the client’s HTTP request (except HTTP traffic destined for the Zyxel Device) to a
web proxy server. A proxy server helps client devices make indirect requests to access the Internet or
outside network resources/services. The web proxy provides caching service to allow quick access and
reduce network usage. The proxy checks its local cache for the requested web resource first. If it is not
found, the proxy gets it from the specified server and forwards the response to the client.
24.2 SMTP Redirect
SMTP redirect forwards the authenticated client’s SMTP message to a SMTP server, that handles all
outgoing e-mail messages. The Zyxel Device forwards SMTP traffic using TCP port 25.
