Network Configuration Guide: SAP/EDS Server behind a router with firewall

  • Step 1 of 3: Firewall

    Incoming traffic

    Most computer networks these days are protected by firewalls blocking any unwanted communication between computers in your network and the Internet. In order for Enterpryze to work, some communication has to be permitted.

    Your local network and – more specifically – your SAP Server has to be able to communicate with the Enterpryze Cloud. There are 7 network (IP) addresses:

    Your firewall (we can safely assume, you have one in place), has to permit the communication with those 7 addresses, so a rule has to be added in your firewall configuration, to permit INCOMING traffic on PORT 8099*, from and to the above listed IP addresses – and just them, nobody else (meaning: no other IP addresses should be allowed access).

    *NOTE: If your installation is using a port number different from 8099, please adjust this setup accordingly.

    Outgoing traffic

    Most computers behind firewalls can access the Internet to use e.g. WWW – the websites. You might want to make sure that your SAP Server can access the following website:


    If your server cannot navigate to that site, you may require some specialist help from our support, as it is likely you have some extra security measures in place.

  • 1.1 SAP version

    Once your firewall lets Enterpryze Cloud read and write information, the route has to be established for that information to be transferred from the Internet to your SAP Business One Server – and the Enterpryze Data Service running alongside your SAP installation.

    In order to do that, a PORT FORWARDING setup has to be completed for port 8099, between your router and the server where the Enterpryze Data Service is running.

    Example Port Forwarding configuration screens from a popular range of routers:

    Add the port to be forwarded – in here the non-standard port configurations are called “custom services”, so we are adding a services:

    With the new service (port) configured, we can put them into use for port forwarding itself (please mind the IP address – yours will very likely be different than the one used in this example):

    Congratulations – configuration complete!
