ISA550 - Setup a private LAN

I have a good idea of how to do this but I don't have time for experiments so I thought I would get some expert opinions.

I have a fairly simple network - Public IP WAN to Private network LAN and everything is fine.  The owner is starting a new business and wants to add another network - (they have another Public IP routed through the first) - and they want this new private LAN to not be able to access the old LAN.  Then, they would like to either have the old LAN access the new LAN OR a third private network (for admins) that can access both with neither of them accessing the other.

I'm looking for the BEST way to do this.

Thanks

Re: ISA550 - Setup a private LAN

Hi,

This should be very easy to configure, I would start with creating a new VLAN (call it Lan2 maybe), then allocating one of the physical configurable ports to it. You should also be able to create a DHCP pool for this LAN2 if you need.

Then use the firewall rules to block access to LAN1 from the LAN2 zone...

Hope that works.

Here is a good link that will help:
