How to Split Tunnel Steam on Mac
Full Speed Downloads, Low Ping Gaming
Key Takeaways
Steam on Mac can be split tunneled to bypass VPN for downloads and gameplay
Games launched from Steam inherit the routing — no per-game configuration needed
SplitTunnel handles this natively with one-click app routing
What Split Tunneling Does for Steam
Split tunneling routes Steam traffic outside your VPN — directly to Valve's servers and game CDNs. Downloads run at full ISP speed. Multiplayer games connect with your real ping. Your VPN stays active for everything else.
- •
Downloads at full ISP speed instead of VPN-throttled speed
- •
Multiplayer connects with your real ping, not VPN ping
- •
Workshop and community features use direct connection
- •
VPN stays active for work apps, browsing, and privacy
Why Steam Benefits from Split Tunneling
Game downloads are massive — 10 to 100GB per title. VPN overhead is negligible for web browsing but significant at this scale. Steam's CDN also picks servers by IP location, and VPN gives it the wrong location.
There's rarely a reason for game traffic to route through a VPN. It doesn't need privacy protection, and the VPN only adds latency and reduces speed.
Method 1: Manual Route Configuration
macOS doesn't have built-in per-app routing. You'd need custom routing rules and packet filter configuration, and you'd have to identify all of Valve's IP ranges (which change). This is fragile, breaks on macOS updates, and isn't recommended.
Method 2: VPN Client Split Tunneling
Some VPNs offer app-based split tunneling on Mac — Surfshark, PIA, and ExpressVPN among the few. But corporate VPNs rarely expose this option, and the implementation is often coarse-grained.
Method 3: SplitTunnel App (Recommended)
Purpose-built for per-app routing on macOS. Works alongside any VPN.
Download and install SplitTunnel
Your VPN connects as normal
Find Steam in the app list and set routing to "Direct"
All Steam traffic now bypasses VPN
Games launched from Steam automatically route direct — no need to add each game individually.
What Gets Routed
When you route Steam direct, everything under the Steam process tree bypasses the VPN:
- •
Steam launcher (store, library, community)
- •
All games launched from Steam
- •
Game updates and patches
- •
Steam Workshop downloads
- •
Steam voice chat
- •
Steam Remote Play streaming
Verifying It Works
Connect VPN as normal
Open Steam and check download speed (Settings → Downloads)
Compare in-game ping before and after
Confirm VPN is still active for other apps (check IP in browser)
