Internal load balance SMTP/POP3 servers

  • Hey All,

    Sorry if this has been asked and answered already. I seem to get hung up on load balanced pfsense

    I have two internal smtp and pop3 servers {shared storage mailboxes}. However when I opened the NAT
    firewall rule I can only specify one destination IP address. Is it possible to set the NAT rule on my Pfsense
    router to allow connections to either SMTP or POP3 server externally? Externally I only have one IP address
    via my ISP. Is this whats hosing me?

    Pfsense 2.0-BETA3

    Please advise…


  • You can either put an alias there with many ips or just use services->load balancer

  • Also, be aware if you're traffic shaping and you're using secure pop3-s / smtp-s, you'll need to add those rules in the TS otherwise, regular mail will be faster than email.
