Title: MCA External IP Addresses
Post by: ralph on March 21, 2013, 03:30:26 PM
I've poured over the engineering docs on this and haven't found it.

I have a MAS in LAN mode.   
The engineering docs says that you need 2 external IP address.   One of them has to map 443 to 4443.
What I can't find is 'Why?'

If I'm doing a one-to-one NAT why would it need a second IP?
It doesn't need one internally.

I can't say why, but my 5000 has 2 external IP addresses and my MAS and AWC each have one.  I think for the 5000, it's for the expansion chassis.

This is what the engineering docs say:

Quote
Have two domain names (or subdomains) available when using address translation.
o External IP address 1 must be routed to Internal IP address 1.
o External IP address 2, port 443 (default) must be routed to Internal IP address 1 port 4443 (default).

Think the second IP is needed for the collaboration part of the MCA.

That's what I suppose.   
I think it allows for external users to traverse firewalls via port 443 and have it reach port 4443.
But where is this FQDN referenced in the MCA config?

If you are running MCA on MAS  4.0 (SP2 I think is the earliest. Ie current version) then you only need the one IP address again now.

One thing to watch out for is if you upgrade an existing install then you need to reconfigure the web proxy, and MCA for the new requirements, as otherwise you will get people complaining that they can't collaborate!
