Outgoing traffic blocked


  • Hi,

    I moved a Hyper-v guest to another server (host), but now outgoing traffic is blocked in the hyper-v:

    • Incoming traffic is ok
    • Outgoing traffic is blocked (using telnet <host> <port>) returns timeout, I can't even open any webpage
    • I can ping to any host
    • I can trace route to any host
    • I disabled windows firewall
    • No antivirus installed

    Does anybody have an idea of what could be the problem?

    Thanks in advance.

  • I disabled Windows firewall in both, host and guest, and the problem remains.

    Then windows is not blocking anything. A wild guess is routing. If you need more help then posting an unedited ipconfig /all of source and target might help.
