CWA: install on Access Edge or dedicated server? RRS feed

  • Question

  •  

    Can CWA be run on the access edge server or does it need its own host? Also, anyone got a doc or know off their head what ports CWA needs to talk back to the pool? Is it just 443 and 5061 (That just seems too clean!) ?

  • Hi,

    You will find the ports used by CWA in the Communicator Web Access planning and deployment guide

    Here is the table:

    Table A-1: Default Ports used by Communicator Web Access

    Port

    Purpose

    80

    HTTP (if not configured for HTTPS on 443)

    88

    Kerberos

    137

    NetBios Name Service

    138

    NetBios Datagram Service

    139

    NetBios Session Service

    389

    LDAP on the DC

    443

    HTTPS (HTTP over TLS or  SSL)

    1025 - 65,535

    Dynamically assigned for incoming traffic from Office Communication Server 2007 Server

    3268

    LDAP on the GC

    5060

    SIP (TCP and UDP)

    5061

    SIP (TCP and UDP)


    As for putting the CWA server on your access edge you might want to consider the following:

    - CWA is not supported in the DMZ Area
    - Collocation of CWA and OCS is not supported

    The Access Edge is a DMZ component along with your reverse proxy while your CWA server is an internal component. Simply publish the CWA to your external world through your reverse proxy

    Sincerely,
