    Caspian, would you post a trace to ns1.telstra.net ? Since it looks like ns1 is in Melbourne if i'm not mistaken. Thanks

    edit - trace from a Telstra NBN connection (standard cpe) of a family member which can speak to ns1/0.telstra.net fine:

    AUSNOG is the place for it, its not like telco's have never done layer 4 filtering before :/

    The fact that evilasdeath replicated the issue highlights the crystal clear reproducible nature of the issue, there is already sufficient material for a NOC case, especially as they're a relatively large and local NS provider.

    Sorry OP, I'd share a NOC contact although you're better requesting someone reach out to you, check the AUSNOG posting guidelines or other people's post history.

    looks good now, responds and doesn't time out. Behind Telstra HFC service like before.
