General settings

Maximum connections
value="" /> per Backend.
Sets the maximum per-process number of concurrent connections to X.
NOTE: setting this value too high will result in HAProxy not being able to allocate enough memory.

{$memusage} kB.
"; ?> Current 'System Tunables' settings.
  'kern.maxfiles':
  'kern.maxfilesperproc':

Full memory usage will only show after all connections have actually been used.
Connections Memory usage

1 50 kB
1.000 48 MB
10.000 488 MB
100.000 4,8 GB
Calculated for plain HTTP connections,
using ssl offloading will increase this.
When setting a high amount of allowed simultaneous connections you will need to add and or increase the following two 'System Tunables' kern.maxfiles and kern.maxfilesperproc. For HAProxy alone set these to at least the number of allowed connections * 2 + 31. So for 100.000 connections these need to be 200.031 or more to avoid trouble, take into account that handles are also used by other processes when setting kern.maxfiles.
Number of processes to start
Defaults to 1 if left blank ( CPU core(s) detected).
Note : Consider leaving this value empty or 1 because in multi-process mode (nbproc > 1) memory is not shared between the processes, which could result in random behaviours for several options like ACL's, sticky connections and some others.
For more information about the "nbproc" option please see HAProxy Documentation
Reload behaviour /> Force immediate stop of old process on reload. (closes existing connections)

Note: when this option is selected connections will be closed when haproxy is restarted. Otherwise the existing connections will be served by the old haproxy process untill they are closed. Checking this option will interupt existing connections on a restart. (which happens when the configuration is applied, but possibly also when pfSense detects an interface comming up or changing its ip-address)
Carp monitor
Monitor carp interface and only run haproxy on the firewall which is MASTER.
 
Stats tab, 'internal' stats port
Internal stats port size="10" maxlength="5" /> EXAMPLE: 2200
Sets the internal port to be used for the stats tab. This is bound to 127.0.0.1 so will not be directly exposed on any LAN/WAN/other interface. It is used to internally pass through the stats page. Leave this setting empty to remove the "HAProxyLocalStats" item from the stats page and save a little on recources.
Internal stats refresh rate size="10" maxlength="5" /> Seconds, Leave this setting empty to not refresh the page automatically. EXAMPLE: 10
Sticktable page refresh rate size="10" maxlength="5" /> Seconds, Leave this setting empty to not refresh the page automatically. EXAMPLE: 10
Logging
Remote syslog host
To log to the local pfSense systemlog fill the host with the value /var/run/log, however if a lot of messages are generated logging is likely to be incomplete. (Also currently no informational logging gets shown in the systemlog.)
Syslog facility
Syslog level
Log hostname size="18" maxlength="50" /> EXAMPLE: HaproxyMasterNode
Sets the hostname field in the syslog header. If empty defaults to the system hostname.
Tuning
Max SSL Diffie-Hellman size size="10" maxlength="5" /> EXAMPLE: 2048
Sets the maximum size of the Diffie-Hellman parameters used for generating the ephemeral/temporary Diffie-Hellman key in case of DHE key exchange. Minimum and default value is: 1024, bigger values might increase CPU usage.
For more information about the "tune.ssl.default-dh-param" option please see HAProxy Documentation
NOTE: HAProxy will emit a warning when starting when this setting is used but not configured.
Global Advanced pass thru
 
NOTE: paste text into this box that you would like to pass thru in the global settings area.
 
Recalculate certificate chain.
  (Other changes on this page will be lost)
This can be required after certificates have been created or imported. As pfSense 2.1.0 currently does not always keep track of these dependencies which might be required to create a proper certificate chain when using SSLoffloading.
Configuration synchronization
HAProxy Sync /> Sync HAProxy configuration to backup CARP members via XMLRPC.
Note: remember to also turn on HAProxy Sync on the backup nodes.
The synchronisation host and password are those configured in pfSense main "System: High Availability Sync" settings.
