Hi There,

I'm looking for some advice on what would be the most commercially reliable DSL modem would be to put into a production scenario. I see that there are plenty of them around however I have been caught once before with silly things like single PPTP pass through etc on the cheaper brands. These will be simply terminating the DSL connection and then DMZing the traffic to the WAN port of our Fortigate firewalls. We will be running multiple site to site VPNs across these connections in case that makes a difference.

I'm not trying to start a flame/religious battle on firewalls or routers but hoping someone on here has had some experience in a commercial production environment with a reliable DSL modem.

Look forward to hearing from you :-)
Thanks,

Hayden

Hi Hayden, checkout the Draytek range. They are especially good for your deployment as they will convert pppoe requests from your Fortinet to pppoa on the outside via 'pppoe pass-through'. This gives you a true public IP address on your firewall (i.e. not 1/2 bridged) & the firewall also controls the state of the circuit (great for failover etc). Via firmware there are also choices of different modem tunings for the best possible connection to your local DSLAM.

I'm biased as I sell & support them but def worth you looking into.

I was gonna say Cisco or Draytek. Our retail network currently uses Cisco but I have used Draytek stuff whilst in Europe and it was also very good.

Draytek would get my vote too. So would a Juniper SSG5 with a ADSL2+ card in it, but they're not cheap!

Audiophiles are such twits! They buy such pointless stuff: Gold plated cables, $2000 power cords. Idiots.

OOOHHHH HYPERFIBRE!

Give this one ago - set it up in PPPoA to PPPoE mode, and it will act as pure modem. Your router then connects to it using PPPoE authentication.

Thanks for your help guys. I'll be doing this implementation over the next few weeks.

When you mentioned choice of firmware and best possible connection to the DSLAM... what does that mean exactly ?

Different telco's use different gear in the exchange/cabinets for terminating your line.

If I recall correctly Telecom are using Alcatel-lucent DSLAM/ISAM with IKANOS line cards, Orcon use Siemins for the + network, Vodafone were using Huawei for the red network and Telstraclear using Alcatel-lucent and so on.

There are quirks and different default settings and profiles, apparently Draytek go to the extent of offering mulitple different firmware's optimised for local conditions.
