i2pd configuration ================== i2pd can be configured via command-line arguments and config files. Options are the same, for example, running i2pd with argument `--port=10123` and setting option `port = 10123` in config file will have same effect. There are two separate config files `i2pd.conf` and `tunnels.conf`. `i2pd.conf` is main configuration file, where you configure all options. `tunnels.conf` is I2P tunnel configuration file, where you configure I2P hidden services and client tunnels for you needs. `tunnels.conf` options are documented [here](tunnels.md). INI-like, syntax is the following : = . Comments are "#", not ";" as you may expect. See [boost ticket](https://svn.boost.org/trac/boost/ticket/808) All command-line parameters are allowed as keys, but note for those which contains dot (.). For example: i2pd.conf: # comment log = true ipv6 = true # settings for specific module [httpproxy] port = 4444 # ^^ this will be --httproxy.port= in cmdline # another comment [sam] enabled = true See also commented config with examples of all options in ``contrib/i2pd.conf``. Options specified on the command line take precedence over those in the config file. If you are upgrading your very old router (< 2.3.0) see also [this](config_opts_after_2.3.0.md) page.
