    I'll be honest, the answer is no (not worked with SNA at all)  but happy to try and work it with you if you want. I'll need a fair bit of detail please. Starting with the output of the log file (open the GUI, select monitoring - logging - click on start query, try and make the connection from a client and view the log)

    The VPN application is from Check Point called VPN-1 SecuRemote and the comes the SNA Client which they connects to this IP Address.

    looks like you are blocking the SNA port (1478). This protocol is not in the default ISA protocol set and will need to be added.

    Highlight the firewall policy in the gui.
    On the right-hand side, select the Toolbox tab and then protocols
    Click on new and create a protocol for SNA on outbound (if internal to external) or inbound (external to internal) for tcp port 1478.

    Add this new protocol to the outgoing rule.
    Save the policy.
