PAP2 looses static IP address - HELP!

[jgb1jgb1]

I am trying to set a static IP address on my pap2 but I am having problems making it "stick".
The pap2 keeps the static IP address for some time (hours) but then it gets reset and I loose phone service.
At that point, if I reboot the router (pap2) then the service is restored. This outage usually is discovered by my wife who is not real VOIP friendly. I do not want to have to worry about the service going down.

To set the static Ip on the pap2 I:
Disabe dhcp.
Set the IP address on the PAP2 to xxx.xxx.xx.100.

Then on my main router (Linksys wrtp54g) I:
Set the dhcp ip address range to use .101 to .149.
Set the port forwarding on the wrtp54g for .100

The pap2 works like a champ for a while but then somehow the pap2 gets changed. DHCP is set back to enabled and the ip address I entered is wiped out. The actual ip address assigned to the pap2 is reset to an address in the dhcp range from the wrtp54g.

What am I forgetting to do?
Thanks, jb

VT does auto provisioning every hour which causes your static IP address to change. I believe you can submit a ticket to have them set it to a static IP address but you would probably not get updates or new features without rebooting it every so often.

Or you can turn off the provisioning

My PAP2 is BYOD.
I set it up and let the router (Netgear FVS318) assign it an IP address.
Then I logged into the router and viewed the attached devices.
I then 'assigned' the PAP2 the static address that it had already been assigned. Even after moving some cabling around and rebooting both my cable modem and router, the PAP2 has kept the same static IP.
DHCP and provisioning are both enabled on my PAP2.

I did that too Phallesy but then...after about 5 hours, my PAP2 reset it's own ip address and also reset DHCP to enabled and I lost dialtone.
I got it to work again by rebooting the pap2 but I don't want to have to do that every day.
After ViaTalk turned auto provisioning off I set the static IP address on the PAP2 and set DHCP to disabled.
On the main router I set the allowable ip address range for dhcp to one above the static ip I had just set on the pap2.
Then I assigned port forwarding on the main router to the static ip address and all seems to me working really nicely!
Thanks to all!

I still have my PAP2 using a DHCP address, so I didn't have to get VT to make a change in my settings.

Instead, like mentioned above, I setup a STATIC DHCP in my router. When the router sees the MAC address of the PAP2 doing a DHCP request, the router always gives out the IP I set in the router's STATIC DHCP table instead of any available. In fact, I do this for every computer in my network so I can assign Quality of Service QoS speed settings for each device in my network, with the PAP2 having top priority.

Anyway, if your router has QoS, make sure it is set to give priority to the PAP2 so internet activity/uploads don't interrupt voice quality.

This works well with dd-wrt. Since I am selective on my static dhcp addresses, I make sure that the static address are outside the range of the dynamically assigned ones (but make sure its still part of your network range).

Try setting the pap2 as follows: Dhcp no, Static ip: xxx.100, Netmask: match the router usually 255.255.255.0, gateway xxx.1 (router IP), and DNS to xxx.1 (router IP again)

Then do not assign anything in the router for the pap2 (other port forward or DMZ). Don't assign it an IP address in the router. The pap2 will assign itself the xxx.100. Also, make sure it is the first device to power up after the router. In other words. Power Modem, Router, PAP2, PC, other devices, etc.

Give that a try.

Another thing you may want to check is... see if your router has lease time for IP Address. I don't know your router specifically but some do. If so when that time expires it assigns a new IP.

Do like chas3 recommended and go into your router and look for a place to assign the mac address of your pap2 a specific ip address. After you do this you do not have to go into the pap2 and mess with any DHCP or static ip settings, just leave the pap2 at its default settings with DHCP on.

I considered the MAC address option but the LynkSys WRTP54G does not have this setting available.
This is a semi-locked down Vonage router.

You can always have VT provision your static IP information for you as well.

Well, technically, you're not using a "static" address. You are creating a reservation for a specific MAC address to receive a specific IP address from DHCP. If DHCP breaks, you still won't get an address.

With static addressing, there is no reliance on DHCP.
