Any WinXP firewall experts?

[stookie]

Hey all, this isnt strictly a VBox issue (I think...), but there seems to be some very switched on people here, so I thought Id ask. Right, my setup:

• Wireless network at home, connecting out to the internet
• Desktop Linux PC, on the wireless network
• Laptop WinXP (Prof, SP2), on the wireless network
• The laptop runs VBox (2.0.0), with a Linux guest
• The Linux guest connects to the WinXP host with a Host Interface virtual NIC, with the virtual network on a different subnet to the wireless subnet
• The WinXP host uses the Internet Connection Sharing settings to link the Host Interface network to the wireless network (bridging is out cos of the wireless)

Now, all 3 OSs (Linux PC, WinXP laptop, Linux guest on laptop) can access the internet (ping, http, etc).

The WinXP laptop can ping both the Linux desktop PC and the Linux guest.

The Linux guest can ping both the WinXP host and the Linux PC, as well as SSH to the Linux PC.

BUT, the Linux desktop PC cant access the Host Interface network, either the laptop or the guest, by any method (ping, SSH, traceroute).

Ive made the WinXP firewall as permissive as possible, but even after Ive done this, Ive noticed the following results in the firewall log file:

LinuxPC> ping WinXPLaptop (Host Interface address)

Code: Select all

DROP ICMP WinXPLaptop LinuxPC - - 84 - - - - 0 0 - SEND

LinuxPC> ping LinuxGuest

Code: Select all

DROP ICMP LinuxPC LinuxGuest - - 84 - - - - 8 0 - FORWARD

LinuxPC> ssh LinuxGuest

Code: Select all

DROP TCP LinuxPC LinuxGuest 38109 22 60 S 580832041 0 5840 - - - FORWARD

Obviously Im missing something, but for the life of me I cant find it! Given the log results, Im pretty sure the firewall is blocking the comms, the return comms in the first instance, and the original comms in the second and third.

Ive got SSH configured in the Internet Connection Sharing, the firewall general exceptions, and the advanced settings for both the wireless and Host Interface NICs.

Similarly, Ive got ICMP configured in the firewall general advanced section, and the advanced settings for both the wireless and Host Interface NICs.

Any help or tips would be most appreciated!!!
Thanks...
