Help to set up HAProxy on my pFsense - multiple SSL domains, one public IP

[havastamas]

Hi guys! I need a little help to set up HAProxy on my home lab. First of all: i have multiple domains with SSL on my server. I have a Synology NAS too, and im using some syno applications.

So this is the start point:
1 public ip
2 host
5 domains
4-5 application / host (websites, syno cloud, etc)

Im using pFsense 2.5 dev + haproxy-devel 0.60_4

I cannot find any working tutorial for this situation. There is one domain, and about 3-4 subdomain on it, what im using for my apps (so this domain should point to my synology).
The other 3-4 domain runs on my HP server, im hosting some websites for my friends for free.

I have tired some tutorials, but mostly i got http 503 error. It is possible to get this work? With SSL?

Thanks for your help.
