Sorry, you put your original request in a VBox post so I made some assumptions.

You're trying to ping the router from your PC and not a VBox host, right? I'm not trying to talk down to you, but I don't know your skill level (it may far exceed mine for all I know) and it's best to start from the ground and work up.

Did you change the IP address on the MS Loopback Adapter that you are using to match the router's subnet?
-------------------------------------------------------------------------------------------------------------------------

Try configuring a Virtualbox Host Only Adapter for the cloud, then change the network settings of your VB guest OS to that same HOA.

VBox has built in DHCP, you can disable this per interface, but if your guest OS has an IP address that you didn't set and it's not an APIPA, then you need to manually reset the IP address to an address on the same subnet as the router's interface.

Dear twv,

Indeed i am trying to ping my router from my PC and it works and the same backwards.
The IP address of R2 matches the one on my PC and the OSPF has been set so that connectivity exists between all routers and my PC.
The CCP though fails on my desktop and i have disabled the firewall (NORTON), and windows firewall tells me that it is managed from Norton.

I tried to set up a VBOX but it had problems with GNS3 (it couldn't recognoze the OS) FROM gns3.

I replicated your topology. I didn't find any errors that would keep CCP from connecting. I was able bring up CCP on the physical PC as well as a Windows XP Vbox guest attached to the topo. CCP connected to R2 and the routers behind it with no problems. I even knocked the Vbox guest to 1/2 of the required RAM, and still didn't get a connection issue.

Try pinging R2 with the -t option:
C:\ping -t 192.168.137.2

Let it run for a few minutes and see if it drops packets. Type ctrl+c to stop it and show the typical ping stats.

Put the router's IP address in your web browser's address bar and connect. This will bring up the embedded tool on the router. Play around with it ans see if you get disconnects. If you have problems with it, try a different web browser.

What version of CCP are you using? The one I that downloaded was 2.8. The interface on yours looks slightly different.

The usual attempts to fix this kind of problem start with:

1) Adding 127.0.0.1 to Compatibility View and Trusted Sites
2) Updating Java to the latest version
3) Running it as Administrator
4) Disable popup/script blockers.

@marios

Firstly, thanks for the great detail in your post. There are a couple of things in your config that worry me
Code:
=> show run
autostart = False
[127.0.0.1:7200]
    workingdir = C:\Users\Admin\AppData\Local\Temp
    udp = 10001
    [[3725]]
        image = C:\Users\Admin\CISCO\c3725-adventerprisek9-mz.124-11.XW7.image
        idlepc = 0xffffffffc0000000

The line idlepc = 0xffffffffc0000000 is bad news. I know this has nothing to do with the router you are trying to manage, but I'd suggest that you try and re-calculate the Idle-PC value for your c3725-adventerprisek9-mz.124-11.XW7.image

An Idle-PC value of 0xffffffffc0000000 may indicate that your image is corrupt, or (as recently found the RAM setting is too big - but not in your case)

The other thing I'd suggest is using a different card (something OTHER than C7200-IO-GE-E) on R2
Code:
[[ROUTER R2]]
        ghostios = False
        console = 2102
        aux = 2502
        cnfg = C:\Users\Admin\GNS3\Projects\GNS3_OSPF\configs\R2.cfg
        slot0 = C7200-IO-GE-E
        g0/0 = nio_gen_eth:\device\npf_{1d526c1a-ca88-4ece-8606-c4d6445f3948}


I'd suggest you change this to a C7200-IO-2FE - remember it makes no difference as to how your topology performs as to whether it is fast Ethernet or gigabit Ethernet (or 10Mb Ethernet), so there is no advantage with using the gigabit card (except your configs look more real-world)

Apart from that - follow @twv's suggestions and let us know how you go.
