Lost or never extablished connection with 1050 ?

[bosella]

We use the Nortel 1050 for our VPN. We bench test all components over a broadband connection in the office before sending anything home with anyone. The problem we're having is 2 fold:

A)Some folks that have been up and running with no issues lose their connection. We bring all of the equipment back to the offcie and it bench tests fine. Then we take it to anther users home and it works fine. Send it back home to the original users home and it's nogo.

B)We bench test the equipment and send it home with a user and they get a fresh broadband install and it won't connect. We bring all of the equipment back to the offcie and it bench tests fine. Then we take it to anther users home and it works fine. Send it back home to the original users home and it's nogo.

Our IT folks say they can see the router hit the network but the signal never makes it back to the 1050 to complete the connection so our IT folks tell me the problem lies with the ISP and the ISP say its our equipment. Any suggestions would be greatly appreciated.

Any firewalls lurking about ?

Thanks for the reply. Our IT dept has configured a firewall on the 1050. When we test the unit in house or at a different location, all is good.

Are all users on the same ISP?...i.e. the ones that work as opposed to the ones that don't work. Is there a router behind the users broadband modem? Are they all using the same type of broadband modem and router??

My guess would be something to do with one of those devices. Possibly something to do with NAT??

Dane,

Thanks for the reply. I checked with the IT folks and they say NAT is not the issue. They did have to reset the Contivity box last week and one of my users was able to get to the network, but another user lost their connection the very next day. Coincidental?

Are you providing the all the PC's? If not, you might want to check to make sure they've loaded all the latest Microsoft updates as well as document the hardware being used, software loaded, operating system, etc.

That's a tough one...sound like an ISP issue though.

Good luck...

Thanks for keeping up with this thread. Yes we are providing the PC's all have the updates. In the Home Office user set up we have VOIP and are using Nortel phones along with the Nortel 9115 for power and network connection through the Contivity 1050 box and the users that are not able to access the network get HOSTLESS MODE on the Display of the phone. Someone suggested We discuss IPSEC with the ISP which I will do in the morning.

Thanks again for the help.

Any time there's no IP connectivity to the PBX, or security identifier's are misconfigured, you'll get that message.

I'm assuming since it work's in some cases and doesn't in other's...it's not something simple like mismatched security identifier's (password).

We had a mismatch once between our RLC (reach line card) and the 9115 and we got the HOSTLESS MODE message on our phones.

Good luck...

When we started our second phase of this project it was found that there was an issue with subnets that was the cause of these issues. Nortel provided a solution and we thought that was that. Now this issue looks just like the subnet probem and today our IT guys told me that indeed there is a subnet issue. Is it possible for the IT department to fix an ISP subnet issue (reconfigure the addresses in the 1050)? If our home office user can hook up their personal PC and hit the internet ok but are not able tom hit our network with the 1050 is it truly an ISP subnet issue?

Thank you very much for the replies and most improtantly THANK YOU for your patience with a relative NOOB!
