Testing latency to PIAF, which port to ping?

[lifespeed]

Without going into too many boring details, I am trying to configure my network so the two smartphone Bria endpoints can use a common account configuration both inside and outside my LAN. This would mean the endpoints register to mydomain.com regardless of their location internal/external to my LAN, while the router would have a static route that re-routes requests to mydomain.com to my internal PIAF IP 192.168.0.4 (or PBX.local). As an aside, I can simply register to mydomain.org from inside my LAN, but this seems silly as some latency is added for no reason.

In order to confirm that this is working, I would like to examine the difference in ping times between an internal LAN ping to 192.168.0.4 vs a ping to mydomain.org, which would have some external delay unless the router static route has been properly created. Although I can ping 192.168.0.4 internally, I can't ping a specific port.

How do I go about doing this comparison so I can confirm I have my network set up correctly?

Take a look at Ping Plotter for latency testing.

Then read the section ( ping plotter help ) about VoIP testing.

I have found Ping Plotter to be indispensable as a latency test tool.

Bare in mind that Ping Plotter is a Windows program and I am not generally a Windows user. I have to run it in VM and keep an instance just for that program.

It would make much more sense to do this in DNS. Create pbx.mydomain.com. Use an internal DNS server on your LAN that sends that to 192.168.0.4, then on your primary name server for the domain set pbx.mydomain.com to the public IP.

Yes, I came to this conclusion also. But I only have two windows 7 PCs and a PIAF box, no DNS server.

THe PIAF box could easily run DNS for you; in fact it works around a problem if your internet goes out you lose your SIP extension registrations.

Also a great point, atsak. Most of our installations are behind either pfSense or m0n0wall, so we just create a static entry in the forwarder (dnsmasq).

Yet another reason I would like pfSense instead of my current (powerful, but still SOHO-grade) Draytek Vigor 2130 router. Proper hardware with a small flash drive and low-power i3 processor would push $400, which is steep just to get DNS static routing (?) so I don't have to reconfigure my phones from inside to outside to remove a few milliseconds of delay.
