    Default Does Flow block IPSEC traffic

    Does Flow Jamaica block UDP 500 and 4500 ports for IPSEC traffic? Attempting to setup a site-to-site VPN tunnel between two homes and I am not able to see a connection being established. Currently, not at my home in Jamaica so I can't login to the cable modem/gateway device to review its configuration.

    None of the ISPs in Jamaica block any traffic from what I recall. I suggest having someone use a desktop/laptop and give you remote access so you can check the modem settings. Suggesting TP-Link or Ubiquiti for your VPN setup.
    Knowing the solution doesn't mean knowing the method. Yet answering correctly and regurgitation are considered "learning" and "knowledge".

    IPSEC generally requires two public IPs so you need to know which the modems themselves (modem/gateway 1 -> modem/gateway 2) will be establishing the connection or the devices behind them.

    The next problem you may face is that the public IPs change and the tunnel that you setup drops.

    Can use sites/apps like DynDNS or such to keep things working. Or setup a VPN and use that to connect to a box on site.

    DynDNS can work as long as FLOW does not start using CG-NAT.
