Greetings,
I need some help wrapping my head around how to be redundant.
I have 2 wans; adsl from different providers.
I'll have 2 firewalls, and 2 UPS's one for each firewall.
Each firewall will have:
1. a hot swap raid array (only two HD's set to RAID 1, mirroring).
2. two hot swap power supplies.
Is one UPS per firewall agreeable? I don't know how to do it otherwise.
I can't imagine purchasing 4 UPS's, one for each power supply. Seems
a little overkill. I welcome any input.
Should I think about wiring the electricity to be on two different
circuits? ... and / or dedicated circuit? Help me fill in the gaps
here, I'm lost.
Now for the networking...
I'll have two dsl modems. I'm going to guess that I should have two
switches, one per modem. 2 connections coming from each switch, one per
firewall.
I'll need two IP addresses assigned to each firewall from my providers
(total of 4 ip addresses from providers).
Then I'll need a connection between each firewall for the pfsync.
That is a total of 3 ethernet ports per firewall (2 wan, 1 pfsync) just
for the redundancy; not including LANs.
Can the pfsync connection be a simple cross-over cable, to get away from
needing another switch?
Am I headed in a good direction so far? What should I be thinking?
I know CARP is in the equation, I'll get to that after I understand how
I'm gonna hook this stuff up physically.
Thank you for any feedback.
-Andy
