We have a hardware load balancer that is load balancing several exchange related services to internal virtual IPs (VIP).
My question is can we use a single external Public IP to route the external services into multiple internal VIPs based on service?
External IP: 188.8.131.52
10.1.102.2 - 443 (HTTPS)
10.1.102.3 - 143 (IMAP)
10.1.102.4 - 993 (IMAPS)
10.1.102.5 - 25 (SMTP)
So one external IP, routing traffic internally to different internal IPs based on service. I'm drawing a blank tonight, perhaps I've been thinking on it too much! It's most likely right in front of my face. Any suggestions or recommendations? I'm trying to utilize only 1 external IP for my exchange traffic.
