Hi Nikos,
I'm using?req.ssl_sni directives with haproxy, on tcp mode. Myconfiguration is:
frontend port-443
? ? ? ? bind 0.0.0.0:443
? ? ? ? mode tcp
? ? ? ? tcp-request inspect-delay 5s
? ? ? ? tcp-request content accept if { req.ssl_hello_type 1 }
? ? ? ? default_backend tls-out
backend tls-out
? ? ? ? mode tcp
? ? ? ? stick-table type binary len 32 size 30k expire 24h
? ? ? ? option tcplog
? ? ? ? acl clienthello req_ssl_hello_type 1
? ? ? ? acl serverhello rep_ssl_hello_type 2
? ? ? ? acl 0_ocserv req.ssl_sni -i sslvpn.<hostname>
? ? ? ? acl 1_nginx ?req.ssl_sni -i blog.<hostname>
? ? ? ? acl 2_ipaddr req.ssl_sni -i <ipaddr>
? ? ? ? stick on payload_lv(43,1) if clienthello
? ? ? ? stick on payload_lv(43,1) if clienthello
? ? ? ? use-server ocserv if 0_ocserv or 2_ipaddr
? ? ? ? use-server nginx if 1_nginx
? ? ? ? server ocserv 127.0.0.1:8443
? ? ? ? server nginx 127.0.0.1:7443
However, this only work with OpenConnect client, the reason behind this is lack of stickiness in configuration. As you can see in the log. This problem could be about the stickiness, ?or some other magic.
excerpts from log.

as for anyconnect, its appears to be connected to random random backends (receiving different certs), I think it's because it connects to the IP directly, and req.ssl_sni doesn't take ip addresses as valid parameters.
on the server side (i configured the client correctly, though):
Jan 11 21:03:06 tokyo1 ocserv[3072]: GnuTLS error (at worker-vpn.c:749): The TLS connection was non-properly terminated.
Warm regards,
Quan
