I want to have multiple servers behind a single firewall and access each with a different subdomain.
Currently, I am having to have each server tied to a different port (which my firewall forwards to the correct server), but it would be very nice to be able to type in a subdomain because it is easier to remember and is cleaner.
Here are my vague ideas of how this could work:
1) some functionality in my firewall/switch that I am unaware of.
2) some type of load balancing software which would serve a different internal IP/port depending on which subdomain was requested.
3) some type of webserver that acted as the central hub that decided which traffic to return based on the subdomain.
4) I don't know much about them, but SRV records seem to offer promise - would they relate to this situation?
5) it seems as though there must be some solution to this - I would really like to avoid having to get a separate external IP address for each one of the servers that I want to access externally!
Any idea of which of these things might work?
