I2PTunnel (i2ptunnel/)

Tunnel manager for I2P - bridges local services to the I2P network and vice versa.

What It Does

I2PTunnel creates two-way bridges between I2P and the regular internet:

• Client tunnels - Connect to external services via I2P (HTTP proxy, SOCKS)
• Server tunnels - Expose local services to I2P (websites, IRC, etc.)

Tunnel Types

Type	Direction	Use Case
HTTP Client	I2P → External	Browse .i2p sites
SOCKS	I2P → External	I2P-aware apps
IRC Client	I2P → IRC	Connect to IRC through I2P
HTTP Server	Local → I2P	Host a website on .i2p
IRC Server	Local → I2P	Host an IRC server
Streamr	UDP bridge	UDP over I2P
