HaProxy with 2 websites

slim2016

I've been trying figure out how to deal with this for a few days and I can't figure it out.

I have 2 websites hosted on my home server, both have ssl certificates installed on my server.

one of the website is using port 443 and the other is 4234 (virtual host) on my server.

I can get one of the website to work if i use tcp, the other methods http/https offloading and ssl/https don't seem to working. If I however add another website to tcp then my seconds website starts using the first website certificate and it come up an ssl mismatch error.

Configure a backend for each, and use mode ssl/tcp and configure the proper acl's the SNI name to match and then the action use-backend to use the desired backend.
If it aint working please post your haproxy.cfg (from bottom of settings tab) and probably i can spot where the issue is.

p.s. if you dont want to use 'offloading' then don't use certificates in haproxy frontend, and do NOT select SSL-encryption checkbox on the server configuration, but do still use ssl-checks.

Thanks, your advise worked. This is my current config, if any advice in improving it then please let me know, thanks.

Have you checked https://www.netgate.com/resources/videos/server-load-balancing-on-pfsense-24.html ?

Thanks, looks interesting, will have to go through the video and take some notes when I have a bit more time.

Few things.

health-checks , currently only a Layer 4 check is performed (if the connection is accepted on TCP level.) , if possible try and make that a http-check to verify that Layer7 actually provides a expected/valid http response.
your servers are using IP's in the 172.217 range, are those the actual IP's you use? Or just replaced to anonymize the config a bit before posting? You are aware that these are not supposed to be used on private networks right? If they are truly your public-ip's of the server its okay, if you use this network on your private lan, then you might get into issues using certain webservices that really 'own' these public ip's. private IPv4 space is defined as: 192.168/16 , 172.16/12 , 10/8 where the 172.16/12 does not include 172.217.x.x.

i will change to http from basic, thanks for the advice.

I was using fake ip's - even my fake ip's were wrong LOL, nice catch.

Rico

You don't need to fake RFC1918 addresses when posting, anyone can use them anyway.

Good point.
