The proxy scanner engine will, by default, allow the operating system to decide from what interface to send a query from. However, it may be desirable, to limit the queries from one specific IP, which may perhaps have a descriptive DNS hostname. (e.g. proxycheck.webmaster.com) When you specify an IP, the scanning engine, will ignore the interface that the user connected from, and force the operating system to send the query from the IP that you specify.
You may use the keyword "*" to indicate that the system should decide what IP to send the query from.
/as security proxycheck set query-from 126.96.36.199
/as security proxycheck set query-from *
