Avaya 9600 phones with Sonicwall firewall DHCP question

[paulTB]

Hi

I can successfully configure an Avaya 9600 phone to VPN to a Sonicwall firewall and the phone connects and I have dialtone, buttons, etc. Everything works but I noted that the IP address of the phone was set to the local subnet as opposed to the Virtual DHCP range I have set which gets allocated to Global VPN clients (so I know it works).

Though everything appears to work it does not seem right to me that the phone does not have a virtual IP and if I use a Netgear UTM for example I get a Virtual IP allocated to the phone.

My general concern is that if we roll this out we will have users on similar subnets at home (i.e. 192.168.1.x) and this might confuse the system.

Everything I try to get the DHCP to pass down from the Sonicwall does not work and I have to have the client settings in the VPN set to Manual & DHCP for the VPN to connect.

I wonder what other people had experienced if they had got 9600 to connect (if they had ever bothered to look at the phones IP address !). It's quite a pain to get it working so probably once most people got a dialtone they were happy.

The old Avaya Tektip for setting up VPN phones with Sonicwalls was based upon 5600 phones that had manual Virtual IP settings and never used DHCP for this.

I have a 96XX phone connected to a Sonicwall but it will not Register with the Avaya IP office. DId you have to cahnge anything else on the Sonicwall to get it working?

Which model of 9600 phone are trying to use as only certain models are supported currently (soon to change)

That said the VPN should connect. Can you share your settings you are trying obviously not including things like your WAN IP, pre-shared keys.

There are a number of items that need changing on the Sonicwall depending on if you are using XAUTH or not.
