I have a problem that seems like it should be easy to do, but pfSense hates me.
I have several SMTP servers. I would like to be able to load balance them when one of our LAN servers sends emails. I do not need nor want it accessible from the WAN.
LAN interface: 172.24.0.1/16
Load Balance IP: 172.24.200.254
Pool IPs; 172.24.200.1-4
Yes, they are all in the same subnet.
If I telnet (port 25) directly to the SMTP servers (eg 172.24.200.1) I can connect fine. If I try the same with 172.24.200.254, nada.
I have seen information saying that I need to do NAT Reflection or something, but I can't figure out where, how, or what to add.
