
All gateways in a cluster must have the same configuration


All gateways must have the same number of licensed subscribers

Configuring Destination HTTP Redirection {Destination HTTP
Redirection}
Destination HTTP Redirect provides DNS-triggered redirection of HTTP requests to
one or more portal page URLs configured on the NSE. Portal pages could include
account status, maps, local information, etc.
The NSE will intercept and respond to DNS queries containing configurable strings.
Subscribers requesting a website at that DNS will obtain a DNS response that
contains a “magic” IP address (which is the same value obtained when the subscriber
queries the DNS string “logout.nomadix.com”).
The NSE will process HTTP requests for that “magic” IP address (configurable on the
AAA page), and will reply with an HTTP redirection (which may include a number of
signed redirection parameters) to a configured URL. By following the HTTP
redirection, the subscriber will reach the target URL, and he/she will then be served a
page containing whatever information is relevant (account and/or other specific
information).
