Title: Re: NAT traversal with GnuGK

Hi Malcolm,

 

The GnuGK will be using to connecting different customers as a directory proxy, and solve the problem of some customers’ endpoints are behind NAT.

 

I would like to know the possibility of both approaches you have below, like:

1.       I setup a GK with public IP and any endpoints behind NAT can register and communicate each other. This is the setup I have now with Cisco GK. My endpoints behind NAT can setup calls, but result in one-way audio which I suspect RTP packets are not delivered properly because of NAT.

2.       Or  customer has their own GK behind NAT which can be neighbouring with my GK with public IP. And RTP traffic is still handled fine.

 

Thanks,

Leon

Hi Leon,

I am no gnugk expert, but I kow a bit.

I am not sure from your description what you are trying to do.

Do you want to have a gnugk on a public address, and use it to service
clients at home/small sites sitting behind a NAT type router (such as a
linksys)?

Or, do you want to have the the the gungk sitting on a private address
behind a NAT router (like a linksys)?
