  • Multiple ISP with ISA

    Hi ,

    We are using windows 2003 , and ISA 2004 installed on it . Now we have taken a connectiion from 2 ISP's with differant static IP. Now can any one suggest me the steps to configure the connection.

    Also is there any load balancing facility available with this , so if one ISP Connectivity goes down , no need to switch to another ISP manually , traffic will automatically route to that ISP.

    Thanks,

    That is normally handled by the router rather than ISA

      Can't be done... Not really at least.
      For a supported configuration, migrate to TMG.

        Can too!

        I have used Fortigate, Draytek and Atera firewall models, all with 2 WAN connections. Some with load balancing, others with separation of services.
        But this is not an ISA problem, nor an SBS ONE!

          I think Marcel meant "can't be done with ISA" rather than "cannot be done with router"

            Re: Multiple ISP with ISA

            Teiger:
            She asked for ISA, not for a "third" party device. From Forefront TMG it is possbile to configure this. Don't question my ISA knowledge LOL
            Sure multiple devices can do that, hell even my vigor 2820n I'm using at home can do that. Athough he is probably gone next year...

            However, inbound traffic (for example web services) requires round robin. This might give some issues when you loose one internet connection
            DNS isn't aware that the internet feed is gone

              Hi ,

              Thanks for providing all information ...Is this possible with ISA 2006...if yes i can go for up-gradation ...i am more interested in a software firewall solution as hardware firewall UTM devices are quite costly ...although all functionality is fulfilled with isa accept multiple ISP load balancing ...

              Thanks.....

                Again, no it's supported from Microsoft Forefront TMG. ISA can't do this.
