Enable Port Forwarding on Any Connection

Many modern Japanese internet services (like 'Xpass', 'transix', or 'DS-Lite') use IPv4 over IPv6, sharing one IPv4 address among many users. This makes it impossible to accept incoming connections, preventing you from hosting a game server, remotely accessing your home network (NAS), or even causing connectivity issues on IPv4-only networks like public Wi-Fi.

88MON's Solution: We restore your ability to receive connections. We assign you a public IPv4 address and a block of ports. When traffic arrives at your port, our servers instantly convert and forward it to your home device's IPv6 address. This allows you to safely and easily host home servers, set up remote access, and fix connectivity issues, opening up new possibilities.
