Porthole - Local Port Sharing has been released in version 1.1.0.

The free tool lets Steam friends access local network ports without port forwarding or a public IP address - an alternative to VPN services like Hamachi. The update brings new connection modes, a reworked settings menu, and several bug fixes.

New

• Connection modes: automatic, prefer direct, prefer relay, or force relay.
• Pick your relay location, sorted by latency.
• Reusable static share code, tied to the host’s Steam ID.
• Full friends list with search, including offline and invisible players.
• Customize the name of your hosted app shown in Steam Rich Presence.
• Raised the limit, now you can host up to 250 players (don’t).
• Auto-approve ports now supports an allow-list.
• Copy and paste your port list as JSON.
• Specify port ranges, e.g. 27015-27050.
• Copy logs straight from Porthole settings.
• Crash reporter that sends an anonymized log, with your consent.

Improved

• Cleaner settings, with advanced options behind a toggle.
• Resize the members panel, or drag to hide chat.
• Port detector updates live while open.
• Change app name, password, or visibility while hosting, without recreating the lobby.
• Auto-kick players with mismatching versions; warning badge on members running a different version.
• Connections ramp to full speed much faster now.
• Clearer messages when a connection fails.
• Selectable chat messages, now with avatars.

Fixed

• Friends-only and invite-only lobbies block players who aren’t allowed in.
• Automatically selects a working graphics backend.
• Startup crash on Windows.
• Odd names, chat messages, or app titles can no longer crash Porthole.
