NTL Broadband (STB) and Netscreen 5GT

[Guest]

Archived from groups: comp.security.firewalls (More info?)

Hi there,
I'm canvassing for some help..

I'm trying to get a netscreen 5GT working on an NTL Broadband connection.

There are lots of quirks about the NTL connection needing to 'authorize' the
connecting Ethernet MAC address, and I think I've done all the steps (reboot
STB.. reboot firewall..)

The crux seems to be that the netscreen fails to lease an address from the
NTL connection.
I have tested the netscreen on my work LAN and the NT4 DHCP server quite
happily leases it an address..
I've tried a PC on the NTL connection and this leases an address...
But the Netscreen.. nada.. zip..

Anyone got any ideas?

P.S. NTL is a UK cable ISP, and the NTL connection has the PACE 'Set Top
Box'...

Thanks

David

Hi David

I'm on the same service; you need to program the MAC address of the computer
that you used to register your NTL broadband into the netscreen.
I use an edimax wireless router, didn't work until I did this.
All the best,
Matthew

Hi Matthew,
Netscreens don't support MAC address spoofing as it compromises the layer 2
security.

Reverse thinking I put the Netscreens MAC address onto the PC's NIC and
registered that.. registration worked and could access stuff from the PC..
However I was still unable to use the netscreen. It appears that the
netscreen is having difficulties leasing the IP address from NTL..
This seems to be something NTL and Netscreen specific.

Knowing how popular the netscreens are for corporate and business networks,
I assumed that someone has done this before and had the same issues.
Especially as some executive apartments have 'tied' agreements between the
landlord and NTL and you are not permitted to install satellite or BT..


thanks anyway
David

No.. not really a level I wanted to have to dig into

As NTL is quit a big ISP over here I was hoping that someone would have got
this working.
and could point out where I've gone wrong.

Until you do so there isnt much point in asking why.

The win32 port of ethereal is point and click.

I am aware of NTL, I had the misfortune to be one of their customers at one
time.
