    		•
    Additional Configuration
    Whitelist Flows
    Select to whitelist flows for XMPP traffic.
    Use Relay Actors
    Select to use relay actors while configuring Application Relay for RTCP monitoring.
    Options
    Specify an option:
    • For RTCP (Core Avaya SBC): End-to-end Rewrite, Hop-By-Hop Traceroute, and Bridging.
    • For RTCP (DMZ Avaya SBC): Hop-By-Hop Traceroute.
    • For RTCP (Remote Avaya SBC): End-to-end Rewrite and Hop-By-Hop Traceroute.
    Note:
    These options are available only when you select the Use Relay Actors check box.
    The remote port must be configured to the port of the file server. If port 443 is required, TCP should be used. Both Remote port and Listen port, must be the same. To support firmware downloads, use port 80 for listen port and remote port fields. If the ports used are different, configure multiple relays using the same IP address. If the same port needs to be reused, then a different external IP address must be configured using the Network Management feature.

    Reverse Proxy tab

    Name
    Description
    Service Name
    Reverse proxy file name.
    Enabled
    Enables the reverse proxy service.
    Listen IP
    External Avaya SBC IP address and network name.
    Note:
    Use a different IP address for SIP signaling and media.
    Listen Port
    80 for HTTP.
    443 for HTTPS.
    Listen Protocol
    Protocol published towards remote workers for downloading the file,
    Listen TLS Profile (TLS Server Profile)
    TLS profile to be used if HTTPS listen protocol is selected.
    Server protocol
    Protocol used for the Avaya SBC server.
    Server TLS Profile (TLS Client Profile)
    TLS profile to be used if HTTPS server protocol is selected.
    Listen Domain
    Listen domain for the Avaya SBC server.
    Connect IP
    Network name and IP address that Avaya SBC uses to communicate with file servers.
    Load Balancing Algorithm
    Algorithm used for load balancing for the reverse proxy.
    Available options include:
    • Round-Robin
    • IP Hashing
    • Least # of Connections
    Note:
    When you select the load balancing algorithms for Reverse Proxy, you must configure Avaya SBC services to ensure that no other service is listening on port 80. For example, the Load Monitoring service (Network flowsAdvanced optionsLoad Monitoring) to monitor Turn services traffic listens on port 80 by default. You must ensure that these conflicting services should not be used simultaneously.
    PPM Mapping Profile
    Specifies a PPM Mapping profile.
    Reverse Proxy Policy Profile
    Reverse proxy profile to be used for this reverse proxy entry.
    Rewrite URL
    Enables rewriting URL.
    Whitelisted IPs
    Specifies up to five IPs to be whitelisted.
    Server Addresses
    Server IP address and port number.
    Received Server Host
    Received Server Host field, select the SAN or CN field of the certificate associated with the TLS server profile.
    Note:
    For any mismatched or non-SNI request with Reverse Proxy Profile configured:
    • Without Any option in Received server host: Avaya SBC serves the first server configured with the received server host, with TLS server profile configured with SNI Options as Optional or Mandatory.
    • With Any option in Received server host: Avaya SBC serves the server TLS profile certificate configured with the received server host, with TLS server profile configured with SNI Options as Optional or Mandatory.
