Load Balancing and Failover for SMTP and IMAP
I will setup a new HA mailsystem. For firewall i'm using pfsense so why not use the pfsense also for HA/loadbalancing.
The question is how to implement that.
There will be 2 ident mailserver with glusterfs. So the maildata is on both server. Now i need to setup the loadbalancer. I found the loadbancing from pfsense and on the other side the haproxy. This is the one part. The other part is that i need to have 1:1 nat.
How can this be done?
If this is the wrong forum please move this topic.
Ok i think with the integrated loadbalancer i get this to work. Do i need for every service like smtp, imap,… an own ip address? I don't have so much ips to waste them.

No. You can have on ip for many services.
