Proxy Fallback Intvl	This parameter sets the delay (sec) after which the PAP2T
	will retry from the highest priority proxy (or outbound
	proxy) servers after it has failed over to a lower priority
	server. This parameter is useful only if the primary and
	backup proxy server list is provided to the PAP2T via DNS
	SRV record lookup on the server name. (Using multiple
	DNS A record per server name does not allow the notion of
	priority and so all hosts will be considered at the same
	priority and the PAP2T will not attempt to fall back after a
	fail over).
	The default is 3600

Proxy Redundancy	The PAP2T makes an internal list of proxies returned in
Method	DNS SRV records. In normal mode this list will contain
	proxies ranked by weight and priority.
	If the parameter Based on SRV port is configured, the
	PAP2T creates a list in normal mode first, and then inspects
	the port numbers based on the 1st proxy’s port on the list.
	The default is Normal.
