9608G VPN goes to Discover after Login

9608G VPN goes to Discover after Login

9608G VPN goes to Discover after Login

(OP)
I have an R11.1 that I am trying to get to work remotely. The VPN on the phone successfully opens and I get as far as the Extension Login prompt. As soon as I hit # after the password, the phone goes to Discover. I think I must be missing something in the IPO at this point? Even after the phone goes to Discover, Monitor continues to tell me if found the extension number.

Sounds like the IPO does not have a IP route back to the network the phone is on.

RE: 9608G VPN goes to Discover after Login

Can you ping from the IPO to the phone and vice versa?

As kwing112000 mentioned, do you have a IP Route going back to the phone's VPN?

RE: 9608G VPN goes to Discover after Login

(OP)
I cannot ping either direction. I made an IP route, but I wonder if it's wrong. The phone in question is using 192.168.2.50 (or .51, 52 etc.)

The router at the home office is 2.1

I have changed the IP route a few times. Currently I have:

IP Address 192.168.0.0
GW 255.255.255.0
Gateway 192.168.2.1
Destination LAN1

I have also tried 192.168.2.50 as the first entry.

The home network is 1.1 and I have tried that too, with no luck.

RE: 9608G VPN goes to Discover after Login

(OP)
When I say "home office" I mean corporate office.
Home network is the user's home.

RE: 9608G VPN goes to Discover after Login

So the phone boots up on the home user's 192.168.1.x network and connects to HQ via built-in VPN. What is it connecting to, exactly? What terminates/authenticates the VPN? What gives DHCP to the VPN user(phone) after it authenticates?

What is the IP address of the phone? Does SSA show it as a connected extension?

My money is on routing isn't correct within whatever device the phone is VPN-connected to.

Typically your VPN phone would authenticate/connect to the firewall, which will have it's own DCHP scope for VPN users that's separate from the internal LAN(s). Then you have Access Policies in that firewall allowing addresses/ports from the VPN to whatever they're allowed to access.

RE: 9608G VPN goes to Discover after Login

(OP)
nnaarrnn, I appreciate the response. The phone boots up on the home network and connects to HQ via the built-in VPN. Corporate has a SonicWall SOHO 250 and I can see that the VPN is established and staying up. The home network is using 192.168.1.10 to establish the VPN.

The phone is getting DHCP from the SonicWall and has an IP address of 192.168.2.51.

I can see in Monitor that 192.168.2.51:port# is trying to register. Monitor says "found number <233>" and there is also an "RasMessage = gatekeeperConfirm"

I have an IP route in IPO from the home network, 1.0 to the IP address of the IPO, going to LAN 1.


RE: 9608G VPN goes to Discover after Login

IP route in IP Office needs to be

192.168.2.0 (The remote worker's subnet)
255.255.255.0
192.168.1.X (IP address of the SonicWall on the Corp network)
LAN-1

RE: 9608G VPN goes to Discover after Login

(OP)
Changing the IP Route does not make a difference. Monitor is saying the same as it always has:

10:42:28 271603mS RasRx: v=IFace=LAN1, Src=192.168.2.51:49302, Dst=192.168.2.195:1719 peb=0
RasMessage = gatekeeperRequest

10:42:28 271603mS H323Evt: Recv GRQ from 192.168.2.51:49302
10:42:28 271604mS H323Evt: e_H225_AliasAddress_dialedDigits alias
10:42:28 271604mS H323Evt: found number <233>
10:42:28 271604mS RasTx: v=Src=192.168.2.195:1719, Dst=192.168.2.51:49302 peb=0
RasMessage = gatekeeperConfirm

RE: 9608G VPN goes to Discover after Login

(OP)
NAT Traversal is not enabled. sad

Someone else told me ports 1718, 1719, and 1720 need to be opened on the SonicWall. I either can't find how to do that or I lack the appropriate access level. Interested in knowing if you agree or disagree.

RE: 9608G VPN goes to Discover after Login

It's an IPSec VPN, you don't have to open anything on the SonicWall.

RE: 9608G VPN goes to Discover after Login

Be sure that H.323 Transformations (VoIP section of Sonicwall config) is disabled.

RE: 9608G VPN goes to Discover after Login

(OP)
Thanks for all the suggestions. H.323 Transformations was disabled.
I'm out of ideas and called another company for help. They told me that they have never been successful with the VPN client and suggested a VPN appliance at both ends.
I'm happy to pay for help if anyone has any other ideas. Otherwise we'll be getting another SonicWall.

RE: 9608G VPN goes to Discover after Login

(OP)
Derfloh was able to complete the Sonicwall settings to get this phone workings. The Sonicwall needed a different DHCP pool for the phone and permissions for the traffic through the firewall had to be allowed. Obviously he could explain it better than I. Kudos to him!
