BlackBerry Proxy
 properties

The following tables describe the properties that you can configure for each of your organization's
BlackBerry Proxy
 instances.
Property
Description
Default
Restart
gp.gps.max.sessions
Maximum number of active sessions.
15000
—
gp.gps.dns.server.ttl.ms
Time to wait, in milliseconds, for the DNS server response.
1800000
—
gp.gps.server.flowcontrol
Specify whether flow control is enabled for the server.
Off
—
gp.gps.tcp.keepalive
Specify whether TCP keepalive is enabled for the server.
Off
—
gp.gps.unalias.hostname
For DNS lookups of app servers, use either IP address or hostname.
If you select this option,
BlackBerry Proxy
 uses reverse DNS lookup with IP address of app server.
If you don't select this option,
BlackBerry Proxy
 uses the app server hostname for DNS lookups.
Off
Yes
gps.directconnect.supported.ciphers
Add or change cipher suites that encrypt bridging and communications made through
BlackBerry
Direct Connect
.
You may choose to have your own proxy server configured for
Direct Connect
 and placed between your client devices and the
BlackBerry Proxy
 server. If you have added your own proxy server, make sure that the
BlackBerry Proxy
 server ciphers correspond to those required by your own proxy server.
All ciphers must be supported by
Java
.
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_AES_256_CBC_SHA256,TLS_DHE_RSA_WITH_AES_256_CBC_SHA,TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDH_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA
Yes
gp.directconnect.
supported.protocols
Add or change the cryptographic protocols that you want your system’s direct connect bridge to support.
TLSv1, TLSv1.1, TLSv1.2
Yes
gp.eacp.command.service.nslookup.srv.ldap
Enables LDAP over TCP for Active Directory servers. Active Directory servers offer the LDAP service over the TCP protocol; therefore, clients find an LDAP server by querying DNS for a record of the form: _ldap._tcp. DnsDomainName.
If you select this option,
BlackBerry Proxy
 uses LDAP for nslookup of a given service hostname.
If you don't select this option,
BlackBerry Proxy
 uses reverse DNS lookup directly, using the service hostname that you provide.
Off
Yes
gc.mdc.hb.timeout
Specify the heartbeat timeout.
0
—
gp.server.secure.ciphers
Add or change cipher suites that encrypt communications made through a
BlackBerry Proxy
 server.
All ciphers must be supported by
Java
.
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_AES_256_CBC_SHA256,TLS_DHE_RSA_WITH_AES_256_CBC_SHA,TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDH_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA
—
gp.server.secure.
