Issues with SS7 Firewall


Recommended Posts

Hello,

 

I am running SS7 on a Win 7 64b machine.  I have some Workstation 8 VMs running on this machine.  Some of the applications on the VM read and write to files in shared folders on the host machine.

 

I am finding in a VM (Win7 64b) that I use frequently with files on the host,  that there is often a delay in reading files from the shared folder, and in saving.  At times the save fails with an error message indicating the file is in use.  Sometimes after failing to save the file, I get a message that the file on the host has a newer timestamp than that in the VM.  At other times there is no delay.

 

The only thing that I can see that might be interfering with the files is the firewall.  If I disable the firewall, there is no delay, and the saving is consistently quick, as was the case before SS7 was installed.

 

There are very few applications running on the host machine.  Much of the time, it is only the VMs.

 

The IP address of the VM is in the range of trusted IP addresses in Zone Setup.

 

The folders are excluded from Antivirus scanning.

 

Can you suggest any other configuration options that I might be missing that will enable the VM to access the host folders without the delay.  I am not an expert in the settings, and my reading of the situation may be incorrect.

 

TIA

 

Sue

Whenever firewall blocks certain communication and you need to determine the reason, enable logging of blocked communications in the IDS setup, reproduce the issue and then check the firewall log for detailed information about the rule that blocked the communication.

 

Please copy & paste the appropriate firewall log entries here.

Hello Marcos,

 

Thank you for your reply.

 

These are the entries in the log for the Personal Firewall at a time when a message relating to the file being in use was displayed.

 

The VM is 192.168.1.8.  The host is 192.168.1.9

 

The application was trying to save a file.

 

I'm not sure if it is clear from my previous post, but the problem is not consistent.  I can be working for several minutes without any delay in accessing the files on the host.  Then there seems to be a period when the access is slow - sometimes an error is reported, other times it does eventually complete successfully.

 

There is more than one application affected by this.  Some of the files being read are quite small html files being displayed in a browser on the VM. The browser may report that the file does not exist.  Refreshing the page then displays it.

 

Sue

Hello,

 

I have changed the System Integration setting for the Personal firewall to 'Only scan application protocols'. This has returned performance to what I had before installing SS7.

 

Is this safe ?
