Hi Guys For no reason at all I can see, ASE just stopped working across my network. When I try the suggested 'test' (from the ASE manual) of running the the AITraffic.exe from the SDK in the client, the monitor shows nothing. I don't recall making any changes that may affect SimConnect. I've tried using IP addresses and names, but neither makes a change. Any ideas gratefully received. Here are my simconnect entries... Server: simconnect.xml

<?xml version="1.0" encoding="Windows-1252"?><SimBase.Document Type="SimConnect" version="1,0"><Descr>SimConnect</Descr><Filename>SimConnect.xml</Filename><Disabled>False</Disabled><SimConnect.Comm>  <Disabled>False</Disabled>  <Protocol>IPv4</Protocol>  <Scope>global</Scope>  <Address>mainpc</Address>  <MaxClients>35</MaxClients>  <Port>500</Port>  <MaxRecvSize>4096</MaxRecvSize>  <DisableNagle>False</DisableNagle></SimConnect.Comm>

Server: simconnect.ini

Hi Phil, Just stopped working? How about any firewall software, AV software, or updates to such? Or windows update? Anything that could have triggered a blocking of port 500, ASE, and/or FSX? Or maybe an IP address change? As far as I am aware, IPv4 must use IP addresses instead of names. In .xml, would recommend using direct IP addresses with IPv4, making sure the server is a static IP (not dynamic), and add a local comm section as well as global... Also maybe just a cut and paste issue but the last line is missing (</SimBase.Document>). Please try this with your correct static server IP address:

<?xml version="1.0" encoding="Windows-1252"?><SimBase.Document Type="SimConnect" version="1,0"><Descr>SimConnect</Descr><Filename>SimConnect.xml</Filename><Disabled>False</Disabled><SimConnect.Comm>  <Disabled>False</Disabled>  <Protocol>IPv4</Protocol>  <Scope>global</Scope>  <Disabled>False</Disabled>  <Address>192.168.1.102 (change to your specific server IP address which must be static, not dynamic, and try the actual IP instead of 127.0.0.1)</Address>  <MaxClients>35</MaxClients>  <Port>500</Port>  <MaxRecvSize>4096</MaxRecvSize>  <DisableNagle>False</DisableNagle></SimConnect.Comm><SimConnect.Comm>  <Disabled>False</Disabled>  <Protocol>IPv4</Protocol>  <Scope>local</Scope>  <Disabled>False</Disabled>  <Address>192.168.1.102 (change to your specific server IP address</Address>  <MaxClients>35</MaxClients>  <Port>500</Port>  <MaxRecvSize>4096</MaxRecvSize>  <DisableNagle>False</DisableNagle></SimConnect.Comm></SimBase.Document>

Ensure that Port 500 is open via your firewall software (and/or allow FSX/ASE on both server/client). Does this help?

Hi Damian and thanks for the help. I can't allow ASE access through my Server Firewall, as it's not installed on that PC - it's on the client (which I have now enabled and added port 500). I can't see how to open a specific port number on the Windows7 firewall. I have a hardware router too, Do I need to change that? I never have before. On a temporary basis, I'll try disabling the firewall to see if it makes a difference....

Hi, You can go into advanced settings in Windows Firewall to enable a port "rule". Here is a link to assist: http://windows.microsoft.com/en-US/windows7/Open-a-port-in-Windows-Firewall

Sorry for the delay getting back to you Damian (not been well enough to sim really), but just needed to say 'thanks'. Don't know exactly which bit did the trick, but did all you suggested and now all is well once again in the land of ASE & FSX cheers mate!

Excellent! Thanks for the update, and glad you are up and running!
