Split Tunneling Guide: Selective VPN Routing

Split tunneling allows you to choose which traffic goes through your VPN and which accesses the internet directly. This comprehensive guide covers everything you need to know about selective routing with FreeGuard VPN.

TL;DR (Quick Summary)

• Split tunneling routes some traffic through VPN, some directly
• Benefits: Better speeds for local services, maintain VPN for privacy
• FreeGuard’s approach: GeoIP-based routing (by destination region)
• Use cases: Local banking, regional streaming, work applications
• Setup: Settings → GeoIP Region → Select region

What Is Split Tunneling?

Split tunneling divides your internet traffic into two paths:

Your Device
    │
    ├── Protected Traffic → VPN Tunnel → Secure Access
    │
    └── Direct Traffic → Normal Internet → Local Services

Types of Split Tunneling

FreeGuard currently implements GeoIP-based split tunneling, which routes traffic based on where it’s going geographically.

Why Use Split Tunneling?

Benefits

When Split Tunneling Helps

Problem 1: Bank blocking VPN

Without split tunneling:
Bank → Sees VPN IP → "Suspicious login attempt" → Blocked

With split tunneling (bank's region enabled):
Bank → Sees your real IP → "Normal login" → Allowed

Problem 2: Local streaming service

Without split tunneling:
Local service → Detects foreign VPN IP → "Not available in your region"

With split tunneling:
Local service → Sees your real regional IP → Content plays normally

Problem 3: Work requires local IP

Without split tunneling:
Work system → VPN IP doesn't match policy → Access denied

With split tunneling:
Work system → Your real local IP → Access granted

How FreeGuard’s GeoIP Routing Works

The Process

1. You select a region (e.g., US, CN, JP)
2. FreeGuard loads IP database for that region
3. Traffic is analyzed: Where is it going?
4. Routing decision:
   • Destination in selected region → DIRECT
   • Everything else → VPN TUNNEL

Example: GeoIP CN Enabled

Traffic to Alipay (China IP) → DIRECT → Works normally
Traffic to WeChat (China IP) → DIRECT → Works normally
Traffic to Google (US IP) → VPN → Protected access
Traffic to Netflix (US IP) → VPN → Protected access
Traffic to Unknown site → VPN → Protected by default

Setting Up Split Tunneling

Basic Setup (GeoIP)

1. Open FreeGuard on your PC
2. Go to Settings
3. Find GeoIP Region
4. Select your region (CN/US/JP/KR/RU/IR/ID/AE)
5. Save and Reconnect

Choosing the Right Region

Disabling Split Tunneling

1. Go to Settings
2. Set GeoIP Region to Off
3. Save and Reconnect
4. All traffic now goes through VPN

Advanced Split Tunneling Scenarios

Scenario 1: Expat Banking Access

Situation: American living in Germany, needs Chase Bank access

The problem: Chase flags logins from German VPN servers

Solution:

1. Connect to FreeGuard (server doesn’t matter)
2. Enable GeoIP: US
3. Chase traffic goes direct (your German IP)
4. Other US sites work through VPN

Wait, why does this work?

Chase just wants consistent login patterns. Your German IP is fine as long as it’s consistent. The VPN IP changing each time was the trigger.

Scenario 2: Gaming with Regional Content

Situation: Playing game with Japan-only events while abroad

The problem: Game detects VPN, locks regional content

Solution:

1. Enable GeoIP: JP
2. Game server traffic goes direct
3. General browsing protected
4. Regional content accessible

Scenario 3: Work + Personal Separation

Situation: Remote worker needs work VPN and personal privacy

Challenge: Work requires specific regional IP

Solution:

1. Enable GeoIP for work region
2. Work applications see direct IP
3. Personal browsing through FreeGuard
4. Maintain separation

Scenario 4: China Travel

Situation: Visiting China, need both local and international access

Challenge: VPN for international; direct for Chinese services

Solution:

1. Use Trojan protocol (best for China)
2. Enable GeoIP: CN
3. WeChat, Alipay work (direct)
4. Google, social media work (VPN)

Split Tunneling Security Considerations

What’s Protected vs Exposed

Security Best Practices

✅ Do:

• Only enable GeoIP for trusted local services
• Keep sensitive browsing on VPN
• Disable GeoIP on untrusted networks

❌ Don’t:

• Enable GeoIP just for speed gains
• Use split tunneling on public Wi-Fi
• Route sensitive personal data directly

When to Avoid Split Tunneling

• High-security browsing: Journalism, activism, sensitive research
• Public networks: Airports, cafes, hotels
• Unknown networks: Friends’ Wi-Fi, conference networks
• Maximum anonymity: When you need complete privacy

Troubleshooting Split Tunneling

Issue: Local Service Still Blocked

Symptoms: GeoIP enabled but service doesn’t work

Causes:

1. Service uses CDN in different country
2. Service performs additional checks
3. IP database doesn’t include all IPs

Solutions:

1. Clear cookies and cache
2. Try different browser
3. Some services may have additional blocks

Issue: VPN Traffic Slower Than Expected

Symptoms: With GeoIP enabled, VPN traffic seems slower

Cause: Normal variation, or comparing to direct traffic

Reality check: Direct traffic (GeoIP) is always faster than VPN traffic. This is expected.

Issue: Not Sure If Working

Test method:

1. Enable GeoIP for a region
2. Visit a service in that region → Should work
3. Visit ipinfo.io → Should show VPN IP
4. If both work correctly → Split tunneling working

Issue: Some Sites Within Region Go Through VPN

Cause: IP database gaps for some services

Explanation: Not every IP in a country is in the database. Some may be:

• Recently allocated
• Third-party CDN
• Miscategorized

This is normal and doesn’t indicate a problem.

Comparing Split Tunneling Approaches

GeoIP vs App-Based

Performance Impact of Split Tunneling

Speed Benefits

頻寬效益

Split tunneling 可減少 VPN 伺服器負載：

• 本地影音串流：直接連線（節省 VPN 頻寬）
• 本地下載：直接連線（節省 VPN 頻寬）
• 國際瀏覽：VPN（受保護）

常見問題

我可以只針對特定應用程式路由，而不只是地區嗎？

目前，FreeGuard 支援基於 GeoIP 的路由。以應用程式為基礎的路由已規劃於未來更新中。

Split tunneling 在行動裝置上可用嗎？

FreeGuard 中的 GeoIP 路由目前僅適用於 PC。行動裝置支援依平台而異。

Split tunneling 會造成什麼問題嗎？

很少。大多數問題是：

• 明確需要 VPN 的服務（已在使用 VPN bypass）
• 具有多重地區檢查的服務

Split tunneling 的安全性較低嗎？

對於直接流量，是的——它未加密。這是為了相容性的取捨。請將敏感流量保持在 VPN 上。

我的 ISP 能看到我的 split-tunneled 流量嗎？

可以。直接流量會正常經過您的 ISP。他們可以看到您正在存取那些服務（但若是 HTTPS，則看不到內容）。

Split tunneling 會耗用更多電池嗎？

會稍微增加。路由決策流程只會帶來極小的額外負載。整體影響可忽略不計。
