The reason for having two IP addresses is best explained by an example. Let’s see how a user called
Bob uses the primary and secondary IP addresses.
When Bob is at home he accesses the Gateway from his tablet using wireless. The IP address of his
Gateway is always 192.168.2.100. It never changes. So he makes that his primary IP address. At home
with wireless on, the connection is made using this IP address.
But when Bob is not at home he wants to access his Gateway using BobsHome.homeDNS.org. So he
makes this his secondary IP address. Now when he is out of range of his home network – he is outside
his firewall - the connection is made using the mobile device 3G/4G connection or from some wireless
hotspot. The application converts “BobsHome.homeDNS.org” to an IP address and then connects to
the Gateway.
Tip: This all works because Bob has an account with DynDNS.org. More on that later in this user guide.
Why couldn’t Bob just use “myhome.homeDNS.org” as the one and only IP address? Because of the
way his internet access works it just doesn’t work. The “BobsHome.homeDNS.org” resolves to the
address of his DSL modem – as it should – and then the modem gets confused by a home-side
reference to its own address. This may or may not be similar to your situation and it is offered only as
an example.
Tip: Near the end of this user guide is information on “port forwarding”. Understanding and
configuring the router for this is necessary for the above example to work.
In addition to supplying the IP address of the Gateway by either a four part address or as a DNS lookup
name, you can also set the option "Find Gateway on Connect". In this case the IP address of the
Gateway is found and used to connect. This will only work if the iPhone / iPad is on the same network
subnet as the Gateway. When this option is enabled, when the connection is made this popup shows
that the Gateway discovery process in underway.
There are a few other options to set in the PulseWorx settings before you leave the settings screen and
they are:
Username and Password. If your Gateway has a username and password assigned enter them
in the settings so that they can be passed to the Gateway upon connection.
Client Name. This can be anything that identifies this mobile device.
