Hi,
@Home has given me 5 ips but they all have different gateways. I would like to use one ISA server to allow 4 computers and one NAT box to access the internet. Do I a nic for each external gateway? And would I also need a nic for each internal interface (using the 5 external gateways)?

Thanks!

Hi XML,

You only need one external IP address for the external interface of the ISA Server. I assume that all 5 IP addresses are on the same network ID, and therefore each of gateways you received should be reachable from any of the IP addresses, in the event that you want to bind multiple IP addresses to the external interface.

HTH,
Tom

Hi tshinder,

Can I ask your opinion with this config?

<> NIC1 <> ISP1
Internal <> ISA <> NIC2 <> ISP2
<> NIC3 <> ISP3

1. What do I need to install in ISA to support multiple gateways? I tried putting multiple gateways but it seems that it will only go out to the first one.

2. Any other special config or service I need to add to make the ISA use all gateways in a "load-balacing" way?

your help will be very much appreciated.

Hi SaintLuci,

ISA Server will support a single external interface. However, you can bind multiple IP addresses to that single external interface.

HTH,
Tom
