Hello to everyone. I’m a newbie in proxying anything, please give me some help.
I have 1 Exchange 2019 server.
Internal domain name (inside organisation perimeter) is mail.a.local
External domain name is mail.b.com
I want to set up a reverse proxy for it because i will connect several new external domains to it mail.c.com, mail.d.com etc. I mean i want to redirect external requests to sites mail.b.com, mail.c.com, mail.d.com to just one local server with internal name mail.a.local. Ideally, when i type mail.b.com i want to see mail.a.local Exchange Login Page with only two domain in certificate mail.b.com and autodiscover.b.com. And when i type mail.c.com in browser it should be the same mail.a.local Exchange Login Page but with mail.c.com and autodiscover.c.com domains in certificate.
I setuped ARR ISS with no luck.
I also tried Nginx and almost works except mobile clients.
I think the problem is with different local and external domain names, but i don’t understand how to setup it right.
For now i try HAProxy and i hope it will work.
I have pretty simple config:
global log /dev/log local0 log /dev/log local1 notice chroot /var/lib/haproxy stats socket /run/haproxy/admin.sock mode 660 level admin stats timeout 30s user haproxy group haproxy daemon ca-base /etc/ssl/certs crt-base /etc/ssl/private ssl-default-bind-ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:RSA+AESGCM:RSA+AES:!aNULL:!MD5:!DSS ssl-default-bind-options no-sslv3 defaults log global mode tcp option dontlognull frontend fe_exch_443 bind LOCALHAPROXYADDRESS:443 default_backend be_exch_443 backend be_exch_443 server exch LOCALEXCHADDRESS:443 check
It works for one domain only and i dont know hot to setup it for multiple domains.
Thank you in advance.
