Network hardening / firewall settings

Hi All,

I`m looking for the firewall settings to configure my gateway. Can someone specify which ports are used? Then I can block the rest due to network and security hardening.

Thanks in advance!

Hey @DutchSparky
your system will only bind to a networking port if you ask it to, otherwise, you’re likely interested in the proxy based networking configuration, in which case, you don’t open any ports for incoming connections.

To configure, you would use this section of the networking config, translated into the yaml format holochain binary utilizes.

If you want a specific port and ip, you just set it for the bind_to property


Thanks, So basically only outbound.

Yeah, in many cases
