Title: AWC/MCA Dual External IP Addresses?
Post by: bluewhite4 on October 25, 2012, 04:53:38 PM

I maybe loosing my mind, but didn't the requirement for AW/MCAC on a MAS to have two external ip addresses go away?

Depends what ur running, Mas or vMas?
For Mas, yes two nics, for vMas no only a single nic required.

This would be a physical MAS. Maybe its the wave of vMAS that had me thinking this then...

The number of interfaces, and public IP addresses are two different things. Either way you need two public IP addresses to publish AWC/MCA to the outside world.

Could it be you're thinking about SPLIT DNS?

I have had it working on a single IP and heard of several others also managing to get this working, maybe this is how you have heard it, However as it is an unsupported configuration I would not do it on a customers site and would not recommend it, Every time you get another issue you cant help wondering if its the single IP that causes the issue.

So...  How do you assign two IPs to a single interface?

Sorry I should have clarrified that I am assuming that you are talking about MBG in Server Gateway mode, rather than in DMZ mode.
In DMZ mode you only require the one IP, and it is a supported configuration.

When you go through the shell configuration you can specify an additional IP address in there on the WAN interface. You must also have DNS set up correctly so you end up with mas.domain.com pointing to one IP address, and mas1.domain.com pointing to the additional IP address. Usually I'd get the customer to request an additional /29  or /30 from their ISP.

The documentation on doing it is good, but you have to understand how it should work first, as at first it looks scary!
