Integrating several Internet gateways into one LAN card

But Several Routers using for...?


Regards,
vijay

Few weeks I had a  conversation with one IT guy regarding the same issue and he mentioned  that I can integrate all these together and get a high speed connection  through one LAN card using NAT in ISA 2006 or 2004 not sure which of  them..

Did you slap the guy really hard across the head for not knowing what he was talking about?  Should have.

TMG can run multiple internet connections,...but it may be limited to two,...not sure.

@Kadadi_v
I'll explain my self again, sorry if i wasn't clear enough.
The idea of integrating many routers into One ISA Server will actually provide ease of use for end_users, As I said at work I have 4 ADSL routers, each one has it's own IP address as follows:

ADSL
1- 192.168.0.2
2- 192.168.0.200
3- 192.168.0.210
4- 192.168.0.240

WIMAX:

5- 192.168.0.1
6- 192.168.0.20

The reason for using all of these is mainly to solve the bandwidth problem which is limited here, ADSL 7 gigs per month, WIMAX is 10 Gigs per month.

All of these will make 48 Gigs per month which is enough and cheap instead of using Leased line that will cost around 12 thousand dollars per year with unlimited bandwidth however the several routers will only cost 1000 $ a year.

Is it possible to do something "Anything" through ISA server or any other networking softwares that will integrate all of these routers into one single LAN which the 50 users I have can use as one gateway for their PCs?


LOL @ Pwindell
He invited me to his company and told me that he's going to show me that was 2 weeks ago, I'm going to call the guy and tell him in case no one has experience that here, I wasn't really into arguing with him on the possibility of doing so as he seems to know what he was talking about..

I also thought that to use ISA you must have 2 LANs "One acts as WAN, the other Acts as LAN" but he said no you can use ISA only with one LAN and also do the natting of multiple internet gateways through one "Same NIC" on ISA Server PC.

THANKS FOR U BOTH

Thanks a lot pwindell, I felt ignorant for a while when I talked to this guy even though I had an experience on installing & configuring ISA server.

Unfortunately rainconnect is not usable any longer, so my only option is to set up one Router as WAN.?

Your complete multi-internet connection setup (whatever it is, however it is done) must be done totally upstream from the ISA,...it must not be involved directly with the ISA in any way what-so-ever.

TMG is the first version of what we know as "ISA" to use multiple ISPs,...but it is still going to be limited in how that can be used.

U'r referring to Forefront Threat Management Gateway ?
I'll give it a try with the evaluation version and if it works i'm going to purchase it, at least you will pay once not yearly.

What about Radware ? have you any clue about it?

Yes,... Forefront Threat Management Gateway

Radware.
Never heard of it.

I think this is useful..

Unfortunately that statement is not true.
With Forefront Threat Management Gateway the initial purchase of the product is one off but the web content filtering service is by subscription. You will have access to it on a time-limited basis as part of the trial but when you purchase the product, that service will expire after a while. the NIS updates are part of the service so are not subscription based.

Bear in mind that FTMG is 64-bit only and needs 2008 SP2 or 2008R2.

PWindell is correct regarding the ISP position. With FTMG you have two scenarios and this involves either ISP load-balancing or ISP failover.

Marc Grote does a great job explaining the two and how to use them.

Thanks a lot Keith, you spare me a lot of time ...!

thanks both
