Configuration example #1. FIXEdge's initiator connects to SSL acceptor over Stunnel

Configure stunnel

Initiator FIX session

1. Run stunnel GUI Start from Start

...

1. menu Run  

2. Editstunnel.conf from stunnel system tray icon context menu

...

1. . Add a new SSL service

   Code Block
   title stunnel.conf
   [fix_initiator_session1_tunnel]

...

1. client = yes

...

1. accept  = 127.0.0.1:443

...

1. connect

...

1. = <counterparty_ip>:443

...

1. <counterparty_ip> - ip address of counterparty

2. Reload stunnel.conf from stunnel system tray icon context menu

Configure fix session in FIXEdge

1. Open FIXEdge.properties to specify Initiator FIX session parameters:

   Initiator FIX session

   Code Block
   title FIXEdge.properties
   FixLayer.FixEngine.Session.SSLInitiator.Role = Initiator

...

1. FixLayer.FixEngine.Session.SSLInitiator.Host = 127.0.0.1

...

1. FixLayer.FixEngine.Session.SSLInitiator.Port = 443

   Info
   See Additional properties for SSL configuration also

2. Connect to VPN (if necessary; if not, just skip this step);

3. Start FIXEdge.

Configuration example #2. FIXEdge is a proxy between 2 counterparties.

The current configuration describes the following scenario.

FIXEdge establishes SSL connection to Exchange. The client connects to FIXEdge over SSL. All messages from Exchange are routed to the Client and vice versa.

Stunnel is configured for Incoming and outgoing connections on FIXEdge's side and on the Client side.

Configuration on FIXEdge side

FIXEdge.properties

FIXEdge has two configured sessions: EXCHANGE and CLIENT

FixLayer.FixEngine.Sessions = EXCHANGE, CLIENT
# -----------------[ FIXEdge connects to EXCHANGE as Initiator ] ------------------
FixLayer.FixEngine.Session.EXCHANGE.Role = Initiator
FixLayer.FixEngine.Session.EXCHANGE.HBI = 30
FixLayer.FixEngine.Session.EXCHANGE.Host = 127.0.0.1
FixLayer.FixEngine.Session.EXCHANGE.Port = 444
FixLayer.FixEngine.Session.EXCHANGE.Version = FIX44
FixLayer.FixEngine.Session.EXCHANGE.SenderCompID = FIXEDGE
FixLayer.FixEngine.Session.EXCHANGE.TargetCompID = EXCHANGE
# ... the rest parameters for EXCHANGE

# ----------------- [ FIXEdge accepts connection from the CLIENT] ----------
FixLayer.FixEngine.Session.CLIENT.Role = Acceptor
FixLayer.FixEngine.Session.CLIENT.Version = FIX44
FixLayer.FixEngine.Session.CLIENT.SenderCompID = FIXEDGE
FixLayer.FixEngine.Session.CLIENT.TargetCompID = CLIENT
# ... the rest parameters for CLIENT

stunnel.conf

[Tunnel_for_EXCHANGE]
protocol = proxy
client = yes
accept  = 127.0.0.1:444
connect = <exchange_ip>:443
 

...

[Tunnel_for_CLIENT]
protocol = proxy
accept  = <FIXEdge_ip>:443
connect = 127.0.0.1:8901

Configuration on the Client side

stunnel.conf

[Tunnel_for_FIXEdge]
protocol = proxy
client = yes
accept  = 127.0.0.1:444
connect = <FIXEdge_ip>:443

Client's properties

SenderCompID = Client
TargetCompID = FIXEDGE
Remote host = 127.0.0.1
Remote port = 444

FIXEdge uses Windows certificate store for connection to an Exchange.

1. Import the certificate to windows certificate with a certutil tool

   Code Block
   certutil -addstore -user -f "My" <filename>.crt

2. Configure Windows Certificate store in Stunnel

   Code Block
   title stunnel.conf
   engine = capi

   and configure tunnel for the session requiring SSL Connection

   Code Block
   title stunnel.conf
   [Exchange SSL connection] client = yes engineId = capi accept = 127.0.0.1:8443 connect = <exchange ip>:<exchange port>

   <exchange ip> - Enchange connection IP
   <exchange port> - Enchange connection port

3. Configure Initiator session in FIXEdge.properties

   Code Block
   title FIXEdge.properties
   FixLayer.FixEngine.Session.EXCHANGE.Version = FIX44 FixLayer.FixEngine.Session.EXCHANGE.Role = Initiator FixLayer.FixEngine.Session.EXCHANGE.SenderCompID = FIXEDGE FixLayer.FixEngine.Session.EXCHANGE.TargetCompID = EXCHANGE FixLayer.FixEngine.Session.EXCHANGE.Host = 127.0.0.1 FixLayer.FixEngine.Session.EXCHANGE.Port = 8443 FixLayer.FixEngine.Session.EXCHANGE.HBI = 30 FixLayer.FixEngine.Session.EXCHANGE.RecreateOnLogout = true
