Lost with Edge setup behind Checkpoint firewall RRS feed

  • Question

  • Hello, maybe someone can get me on the right track, the situation looks like this:

    Checkpoint Firewall, managed by 3rd party
    DMZ with IP: 172.31.x.x
    DMZ OCS Standard Edition Access Edge server with one nic, 2 ip addresses configured, nl: 172.31.50.50 and 172.31.50.51
    ISA 2006 server, one NIC in the DMZ and one NIC connected to the LAN (IP: 172.30.x.x)

    LAN:
    172.30.x.x
    OCS Enterprise server with IM and presence activated

    On the external DNS created a DNS record sip.domain.com with the right srv record point to a public IP. The company that manage the Checkpoint firewall configured a rule that the OCS traffic would be delivered to IP: 172.31.50.50. This IP is configured as the external interface on the Edge server.

    My internal clients can connect automaticly with there client, but external users are not able to connect automaticly. The message is that the server is not responding.

    Must I configure the Edge server with another NIC? And must this IP placed in another subnet?

    Any help would be great! and sorry for my bad english...
