Blocked inbound packets with VMWare Fusion and Windows XP guest Machine

I am developing a windows based server application and use VMWare Fusion. My virtual NiC is connected to my iMAC's ethernet port. I have turned the firewall off on both the iMAC and Windows XP machines. I have installed wireshark on both the MAC and Windows XP machine. When I run my application the server app sets up fine on the windows XP machine. When an inbound request comes in I can see the traffic on the iMAC via wireshark and the packets have the correct dest ip and port. The traffic is supposed to go to the windows XP machine but its not arriving. I open up wireshark on the xp machine and the traffic is not present. I am pulling my hair out. Please help!!!!

Running OSx 10.6.4 and VMWare fusion 3.1.0

are you using the network in NAT or BRIDGING ?
Have you any antivirus-firewall (non Microsoft or Apple) installed on the XP Machine or Mac ?

Can you ping your Mac ?
Can you ping your Windows XP ?

Hope this can help.

Bridge mode. The XP machine has zonealarm which I have disabled. I have also shut off the built in MAC firewall. I can ping both devices.

Scratch the ping comment. I cannot ping the guest VM XP machine from the MAC nor any other device. However, when I am on my XP Guest, I can remote desktop into my windows server and what not.

So if you cannot ping your XP Guest from any other device there are some issue regarding the network.
Ping is very simple network connectivity test and is my personal opinion that have to work before anything else can work in your case.

It's seem that your XP Guest can easily do outgoing network traffic but are blocked for the inbound.
Can you check or completely remove ZoneAlarm to troubleshooting this issue ?

Hope this can help you.

well, you were correct. Even though I "disabled" the zone alarm firewall it was still somehow blocking. I had to go through an elaborate uninstall/cleanse procedure before it was fixed. ZoneAlarm would not uninstall using Add/Remove programs. The following is the instructions I used to uninstall ZoneAlarm completely.

if possible, first try to uninstall ZoneAlarm normally from your Start ->
Programs -> ZoneAlarm menu. If this fails, or you want to ensure that all
ZoneAlarm files were removed from the system properly, continue with the
steps below.

Please make sure that you have the latest version downloaded first:


01.) Restart your computer
02.) When you see the screen go black and it starts booting back up keep
tapping the "F8" key (at the top of your keyboard)
03.) This should bring up a menu. Choose Safe Mode off the menu by
using the arrow keys on the keyboard to highlight Safe Mode and press
04.) If you get a message asking to go to Safe Mode, choose Yes. If you
get a help and support window, close this.
05.) Once you are at the desktop, Click Start, My Computer
06.) Click Tools, Folder Options, View Tab
07.) Place a dot next to "Show Hidden Files and Folders"
08.) Remove the check from "Hide Protected Operating System Files
09.) Choose Yes to the warning
10.) Click OK
11.) Double click C:

Note: In the future steps if you do not see any files or folders, please click
the "Show Files" link to view them.

12.) Double Click the Program Files Folder
13.) Right Click the Zone Labs Folder (if present), click Delete, and choose

NOTE: If you cannot delete the entire folder, please open the Zone Labs -
> ZoneAlarm folder and delete out as many of the files listed here as

14.) Close this window
15.) Click Start, My Computer
16.) Double Click the C:
17.) Double Click the Windows Folder (It may also be WinNT)
18.) Right Click the Internet Logs Folder, click Delete, and choose Yes
19.) Double Click the System32 Folder
20.) Right Click the Zone Labs Folder (if present), click Delete, and choose

NOTE: If you cannot delete the entire folder, please open the Zone Labs
folder and delete out as many of the files listed here as possible.

21.) Locate and delete the following files in the System32 folder if they are

- vsconfig.xml
- vsxml.dll
- vsregexp.dll
- vsdata.dll
- vsdata95.vxd
- vsdatant.sys
- vsmonapi.dll
- vspubapi.dll
- vsinit.dll
- vsutil.dll
- vswmi.dll
- zlcommdb.dll
- zlcomm.dll
- zllictbl.dat
- zpeng24.dll

22.) Clear your Temp Directory per the instructions below.

- Go to Start -> Run
- Type %temp% and click OK
- Select all of these files and delete them

23.) Clear the Prefetch folder per the instructions below (Windows XP only).

- Go to Start -> Run
- Type Prefetch and click OK
- Select all of these files and delete them

24.) Remove the necessary registry entries:

*Important Advisory: Deleting registry entries incorrectly may cause
serious problems to your operating system, which may necessitate the
need to reinstall it. Please make sure you are able to perform these
deletions correctly before you decide to edit the entries. If you are not
sure, you should seek help from someone who is familiar with editing the

For information about how to edit the registry in Windows, from your
desktop, click Start -> Run -> and type regedit. Click on Help -> Help
Topics. Under the Contents tab, click Change Keys and Values (this may
be found under the How to... section).

Also, you should always make a backup of the registry before editing it.
You can find this in the same section of the Help files.
