How rounting table looks. You said you are able to ping the default gateway. Does your route table shows the correct default gateway? Use
Code:
route -n
and check the output.
If routing table is correct and you are able to ping the default gateway then you have to check something on the router from which the traffic is going to internet and check whether this machine is allowed to access internet?
It will be good to take a packet trace and see what exactly is going on.
When you say internal network I am assuming private internet network. So that is it you have to check that what happens when you do it via DMZ. As I said it in my previous post it will be good idea to run a packet trace to get more details. A better idea would be running packet trace on both you CentOS machine and the next hop which I am assuming to be your router in DMZ.

hi T3RMINVT0R can you guide me on how to do the packet trace?
You would also want to download wireshark as it is a pretty good tool for taking / analyzing packet captures.
If I am getting it correctly you have physical boxes in DMZ which can connect to internet. Hyper-V is one of the physical box in that DMZ and on top of that you have got CentOS guest running. If my assumption is correct then my first question will be if you are able to connect to internet from Hyper-V machine. If yes then this doesn't appear to an issue with the router / gateway instead it appears to be an issue with the bridge that is configured between guest (CentOS) and the host (Hyper-V)
It will be good to know how it has been set to connect to internet.
Yes pretty much possible. If this is the first Guest on Hyper-V host and if never worked before then it is very much possible to be an issue with Hyper-V. Also, other physical boxes within DMZ with static IP are just working fine that explains.

Yes THEY just don't want to play well with Linux system.. I think so.. but VMWare I think should be fine but cost is one thing.
How significant this box is? If it is not of much importance then you can go with CentOS machine running KVM and on top of that you can create guest VMs.
