I think this is the issue in the mode http frontend:
req_ssl_hello_type : integer (deprecated)
this will not work with "bind" lines having the "ssl"

You haven't told it to use SSL when talking to the servers listening
on :4443. By default haproxy is going to use non-SSL TCP.
Add the `ssl` option to both of your `server` parameters.

*Subject: *SSL load-balancing across multiple HAProxy instances
Hi all,
I'm working on a load-balanced instance using HAProxy, Varnish, and
back-end web servers.
I've successfully tested the new SSL termination feature using dev
build 1.5-dev22-1a34d57 2014/02/03, and it works well, however, I
want to load-balance the SSL terminal feature across more than 1
HAProxy instance like so:
Main HAProxy instance on 192.168.1.5, secondary on 192.168.1.10
Varnish servers on 192.168.1.20 and 192.168.1.30
Previously, I was terminating SSL on the single active HAProxy
(192.168.1.5), and speaking HTTP to the Varnish back-ends. This
works well.
What I'd like to do is
Request comes in to HAProxy on port 443. Request is then load
balanced to the two HAProxy servers in tcp mode to 192.168.1.5:4443
and 192.168.1.10:4443 - maintaining SSL mode until it terminates at
port 4443.
An example config (just the relevant sections) would be this:
listen ssl_relay
bind 192.168.1.5:443
mode tcp
option socket-stats
#option ssl-hello-chk
tcp-request inspect-delay 5s
tcp-request content accept if { req_ssl_hello_type 1 }
tcp-request content accept if { req_ssl_hello_type 1 }
default_backend test
frontend incoming
bind 192.168.1.5:80
mode http
log global
option forwardfor
bind 192.168.1.5:4443 no-sslv3 ssl crt /certs/haproxy.pem crt
/certs/ ciphers RC4-SHA:AES128-SHA:AES256-SHA
mode http
log global
option forwardfor
tcp-request inspect-delay 5s
tcp-request content accept if { req_ssl_hello_type 1 }
backend test

balance roundrobin
# maximum SSL session ID length is 32 bytes.
stick-table type binary len 32 size 30k expire 30m
acl clienthello req_ssl_hello_type 1
acl serverhello rep_ssl_hello_type 2
# use tcp content accepts to detects ssl client and server
hello.
tcp-request inspect-delay 5s
tcp-request content accept if clienthello
# no timeout on response inspect delay by default.
tcp-response content accept if serverhello
# SSL session ID (SSLID) may be present on a client or server
hello.
# Its length is coded on 1 byte at offset 43 and its value
starts
# at offset 44.
# Match and learn on request if client hello.
stick on payload_lv(43,1) if clienthello
# Learn on response if server hello.
stick store-response payload_lv(43,1) if serverhello
server test1 192.168.1.5:4443
server test2 192.168.1.10:4443
http works, and I receive requests on port 443, but this is all I get
from the HAProxy log:
00000000:ssl_relay.accept(0006)=0009 from [192.168.1.2:50496]
00000000:test.clireq[0009:ffffffff]:
00000000:test.clicls[0009:ffffffff]
00000000:test.closed[0009:ffffffff]
It appears that HAProxy is not speaking or passing through SSL to the
frontend on port 4443.
curl -i https://192.168.1.5/
curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown
protocol
So... what am I missing?
Cheers,
