Hello Travel-buddy,
please be informed that analysis of this situation needs more outputs (AVG logs, configuration) from your computers. Please contact AVG technical support from one affected computer through AVG diagnostic utility - http://www.avg.com/filedir/util/support/runner_en.exe - please enter your email address (you want to receive answer to) and description of the situation, plus:
- related IP addresses in your network
- if AVG Firewall profile "allow all" will solve it
Thank you
Hello,
My problem appears to result from my current configuration of the Firewall provided automatically by AVG Internet Security (vrs downloaded: avg_ipw_x86_all_2011_1136a3181) and unfortunately I?ve not yet got my head around the firewall blocking features of this software.
I have 4 machines connected to a D-link 635 Wi-Fi router.
2 machines are desktops running windows 7 and include AVG Internet Security, both machines are set-up as Small Home or Office Network and are on a homegroup, so can share files and printers. The 2 other machines are laptops running windows XP.
One of the laptops is on AVG Internet Security which has been automatically set-up as a Small Home or Office Network, whereas the second laptop is running Zone Alarm Firewall (Free vrs) and AVG Anti-virus (Free vrs).
I recently set-up the router configuration rules to allow me to plug in a USB external hard-drive into the USB connector on the D-Link router to create a ?Network Drive and I also installed the latest vrs of D-Link?s SharePort utility on to the 2 laptops. The SharePort program automatically runs at start-up and will allow a machine to see and then allow the user to manually connect/disconnnect to/from the new ?network? drive, although it only allows one machine to connect at a time.
Results:
? First on the laptop running Zone Alarm Free and AVG Anti-virus Free, the Zone Alarm firewall asked me to ?allow? SharePort, which I confirmed. The network drive then appeared with a drive letter assigned and I?ve been able to automatically see/connect/disconnect to the drive (read/write access).
? With the laptop running AVG Internet Security, initially when I installed SharePort it automatically executed and displayed a box indicating that the firewall must be reconfigured to allow TCP out port 80:20005 and UDP outport: 9303.
? After clicking OK to the SharePort message, the firewall then asked for me to confirm what setting to apply to SharePort, which I chose ?allow all (recommended)? and checked the save for future box.
? The firewall than confirmed Small Home or Office Network was operating.
? I then clicked on the SharePort icon in the tray and it displayed a box indicating the USB drive is not accessible.
? I then checked the Firewall Traffic log, which displayed numerous entries for every 10 seconds:
o Application = SYSTEM
o Log Action = Blocked
o PID = 4
o Direction = Out
o Protocol = TCP
o Remote Port = 20005
o Local Port = starting at 1400 and then incremented by 1 or 2 for each entry
o Remote IP = nnn.168.0.1
o Local Port = 0.0.0.0.
? Next I ran the Firewall wizard and change the setting from Small Home or Office Network to Allow All, which effectively disabled every blocking setting.
? Shareport icon in the tray changed from Red to Green and on clicking allowed me to connect and disconnect to the Network Drive.
? I have subsequently changed the firewall back to Small Home or Office Network and the wizard indicated that it had applied Network 1 settings automatically.
My goal is to have all 4 machines accessing the Network Drive for file sharing and back-up, so would really appreciate a step by step guide as to how I manually change the firewall settings to insure top notch security whilst getting AVG Internet Security firewall to allow access to the Network Drive. Cheers Steve.
