AOS under Firewall

Finance and Operations/AX Technical Forum

Hi, I would like to protect my AOS Server using PIX Firewall. We r using 3 Tier Configuration successfully before. But after the installation of PIX we are unable to get the AOS. I can PING the AOS Server IP. but when trying to connect through the Axapta Client ‘No Navision Axapta Object Server found using the current cliuent configuration’ error message comes. Is there any specific configuration needed to access the AOS with Firewall? we r using VPN to connect our server:

Hi, You should fix the port number where AOS works setting it up in the server-tab of the server configuration. Then open this port AND the port# 2712 in the firewall. br.

  1. Open on firewall port X for AOS. 2. In AOS options (Control Panel\Navision Axapta Object Server and button Settings, tab Server ) set Port number: X. 3. In client options (Navision Axapta Configuration Utility), string Advanced: -aos=Server:X

Hi Make sure you also enable UDP calls if you are using AOS clustering.

Hi, Thanks everybody. I have already tried this 1. In AOS options (Control Panel\Navision Axapta Object Server and button Settings, tab Server ) set Port number: 2000. 2. In client options (Navision Axapta Configuration Utility), string Advanced: -aos=Server:2000 I have also enabled all UDP ports. But this makes my clients very slow. It takes almost double time to log in into the AOS. Is there anything more that I should try?Is there any default port for AOS?

AOS uses port TCP 2712 for actual data transfer. UDP 2712 is for discovery of servers. We have an AOS, which is often used over a VPN connection. I specified the AOS host name in the client config and it works fine. No need to modify ports.

Hi again, When using 3-tier client, double click the activity indicator in the bottom-right corner of the window. In the second tabpage of the window there is a test button where you can test the real latency between client and AOS. If the latency increases up to 30 ms you start feeling some slowness and when latency is about 100 ms it is very difficult to use axapta. The firewall might increase the latency, because it prosess the data by software. Good firewalls do this by hardcoded hardware, others by bad software. If possible, check also that your firewall gives priority to axapta traffic.
