Multiple ADSL lines into ISA Server - 15.Aug.2005 5:26:00 AM

Hi,

I'm currently getting up to speed on all things ISA Server and I have the ISA Server 2004 book on order that will hopefully get me up to speed.

In the meantime, I have a fairly general question that I'd appreciate any comments on. My company wants to start hosting its own web services. Previously we haven't had a public-facing web server, hence our interest in ISA. One problem though is our internet connectivity. It so happens that we have ADSL available, but not SDSL. We could get a Leased Line but it is obviously an expensive solution. We don't want to relocate or co-locate. Our plan is to start with a single ADSL line during the testing phase of our web services and early roll-out, and then to get scalability by adding subsequent ADSL lines. At some point, if things go well, we might move up to a Leased Line.

You can probably see the question coming. Can one just plug multiple DSL lines into the ISA Server? I have had some advice that the way to do this is to have multiple WAN NICs on the ISA Server - say up to 8 - and just plug each new DSL router into a new NIC. But this sounds unscalable and kludgy to me. Is it possible to have a switch in front of the ISA Server, into which n DSL routers are plugged and from which a single line goes to the ISA Server?

Obviously channel-bonding and/or load balancing would be nice, but I can probably live without it (it appears from other posts that purchasing RainConnect would be the preferred way to do this?) But my main concern is scalability. I don't want to be stuck with 256Kb upload speeds if our bandwidth requirements increase.

Any thoughts?

Hi,

Just got the book by the way and am now reading ...

Does this mean I need RainConnect to handle multiple DSL lines or can ISA handle it natively but without the bonding/load balancing?

Simon.
