IP hardphone behind lan to Nat

[FortKnox]

Is it possible to use a IP hardphone behind a lan (say at home) to an Avaya switch that also has a lan ip?

If so, will someone just post the quick and dirty so I can give it a shot, also any settings that may need to be changed on the network-region page would be helpful as well.

Thanks.

I am still having trouble getting my hard or soft phones to work over vpn using a Linksys endpoint, I dont have aother vpn endpoint to test with, if someone does and would be willing to help me test, I would appreciate it.

On your home router, just port forward the 1719 udp, 1720 tcp and the range of udp on the netork region to the ip of the hardphone

In the future everything will work...

What ports do I need to nat to the phone switch?

OK,

The phone is 192.168.223.106

On my home router I just put it in the DMZ so that all traffic will go to it.

The phone is stuck on the 'Discover' screen.

On the Avaya when I do a list trace ras ip-address this is what I see:
18:04:27 rcv GRQ endpt 68.111.51.215:49304 switch 192.168.0.40:1719 ext
18:04:27 snd GCF endpt 68.111.51.215:1112 switch 192.168.0.40:1719 ext 418
18:04:32 rcv GRQ endpt 68.111.51.215:49304 switch 192.168.0.40:1719 ext

But in my firewall on the Avaya side, I dont see that the Avaya is making any attempt to go back out.

Take it off the dmz and port forward the above ports to 192.168.223.106

In the future everything will work...

If it is stuck on discover, 1719 udp and 1720 tcp are not open. Those two ports carry the signalling. the udp range in the network region is what carries the voice. If you are going over a vpn to your pbx, you will need to add the ip subnet your vpn assigns to your ip-network-map and assign it a network-region.

In the future everything will work...

OK,

for my home I forwared 1719 & 1720 tcp/udp to 192.168.223.106 (the IP phone)

and on the firewall at work, I forwarded 1719 & 1720 tcp/udp from a public ip to the private ip of the Avaya.

On the Avaya's firewall, I only see incoming 1719 udp requests, and I never see the private ip of the Avaya trying to go back out.

Is your VPN Firewall on the same subnet as your pbx?

In the future everything will work...

When I use the vpn I get that 2011 issue.

I was going to try to see if I could get the phone to work by just doing NAT and port forwarding.
