Can I Bypass Tunnelling While In Home Network?

Understanding the Issue

When you're connected to your home network, you might expect to access your local services without going through a Virtual Private Server (VPS) or a reverse proxy. However, if you're using a tool like Pangolin to manage your services and make them accessible outside your network, you might find that traffic is still routed through the VPS even when you're at home. This can lead to increased data usage and potential performance issues.

The Problem with Tunnelling

Tunnelling, in this context, refers to the process of routing traffic through a VPS or a reverse proxy to access local services. While this is useful for making your services accessible from outside your network, it can also cause issues when you're connected to your home network. The problem is that the tunnelling process can create a loop, where traffic is routed through the VPS and then back to your local network, resulting in unnecessary data usage and potential performance issues.

Exploring Solutions

So, can you bypass tunnelling while on the same network as your home server? The answer is yes, but it requires some creativity and potentially some additional configuration. Here are a few possible solutions:

1. Using a Local DNS Server

One approach is to use a local DNS server to resolve domain names to IP addresses of your local services. This way, when you're connected to your home network, your device can resolve the domain name to the local IP address, bypassing the need for tunnelling.

Configuring a Local DNS Server

To set up a local DNS server, you'll need to install a DNS server software on your home server. Some popular options include BIND, Unbound, and PowerDNS. Once installed, you'll need to configure the DNS server to resolve domain names to IP addresses of your local services.

For example, if you have a Jellyfin media server running on your home network, you can configure the DNS server to resolve jellyfin.my.domain to the IP address of the Jellyfin server. This way, when you're connected to your home network, you can access Jellyfin by visiting jellyfin.my.domain in your web browser, without going through the VPS.

2. Using a Reverse Proxy with a Local IP Address

Another approach is to use a reverse proxy with a local IP address. This way, when you're connected to your home network, the reverse proxy can forward traffic to the local service without going through the VPS.

Configuring a Reverse Proxy with a Local IP Address

To set up a reverse proxy with a local IP address, you'll need to configure the reverse proxy software to listen on a local IP address and forward traffic to the local service. For example, if you're using Nginx as your reverse proxy, you can configure it to listen on localhost:8080 and forward traffic to the Jellyfin server running on localhost:8090.

3. Using a Split-Horizon DNS

A split-horizon DNS is a type of DNS configuration that allows you to resolve domain names to different IP addresses depending on the network you're connected to. This can be useful for bypassing tunn while on the same network as your home server.

Configuring a Split-Horizon DNS

To set up a split-horizon DNS, you'll need to configure your DNS server to resolve domain names to different IP addresses depending on the network you're connected to. For example, if you have a Jellyfin media server running on your home network, you can configure the DNS server to resolve jellyfin.my.domain to the IP address of the Jellyfin server when you're connected to your home network, and to the IP address of the VPS when you're connected to a different network.

4. Using a VPN with a Local IP Address

Finally, you can use a VPN with a local IP address to bypass tunnelling while on the same network as your home server. This way, when you're connected to your home network, the VPN can forward traffic to the local service without going through the VPS.

Configuring a VPN with a Local IP Address

To set up a VPN with a local IP address, you'll need to configure the VPN software to listen on a local IP address and forward traffic to the local service. For example, if you're using OpenVPN as your VPN software, you can configure it to listen on localhost:1194 and forward traffic to the Jellyfin server running on localhost:8090.

Conclusion

In conclusion, bypassing tunnelling while on the same network as your home server is possible, but it requires some creativity and potentially some additional configuration. By using a local DNS server, a reverse proxy with a local IP address, a split-horizon DNS, or a VPN with a local IP address, you can bypass the need for tunnelling and access your local services without going through the VPS.

Best Practices

When implementing any of these solutions, keep the following best practices in mind:

  • Use a local IP address: When configuring a reverse proxy or a VPN, make sure to use a local IP address to avoid going through the VPS.
  • Configure DNS correctly: Make sure to configure your DNS server to resolve domain names to the correct IP addresses, depending on the network you're connected to.
  • Test thoroughly: Test your configuration thoroughly to ensure that it works as expected and that you're not introducing any security vulnerabilities.
  • Monitor performance: Monitor your performance and data usage to ensure that you're not experiencing any issues with your configuration.

Q: What is tunnelling, and why do I need to bypass it?

A: Tunnelling refers to the process of routing traffic through a Virtual Private Server (VPS) or a reverse proxy to access local services. While this is useful for making your services accessible from outside your network, it can also cause issues when you're connected to your home network. Bypassing tunnelling can help you access your local services without going through the VPS, reducing data usage and potential performance issues.

Q: How do I configure a local DNS server to bypass tunnelling?

A: To configure a local DNS server, you'll need to install a DNS server software on your home server and configure it to resolve domain names to IP addresses of your local services. You can use a tool like BIND, Unbound, or PowerDNS to set up a local DNS server.

Q: Can I use a reverse proxy with a local IP address to bypass tunnelling?

A: Yes, you can use a reverse proxy with a local IP address to bypass tunnelling. This involves configuring the reverse proxy software to listen on a local IP address and forward traffic to the local service.

Q: What are the benefits of bypassing tunnelling?

A: Bypassing tunnelling can help you access your local services without going through the VPS, reducing data usage and potential performance issues. It can also improve your overall network performance and reduce latency.

Q: Are there any security risks associated with bypassing tunnelling?

A: While bypassing tunnelling can improve your network performance, it can also introduce security risks if not configured correctly. For example, if you're using a VPN with a local IP address, you may be exposing your local services to the internet, which can increase your security risk. Make sure to configure your VPN and DNS server correctly to minimize security risks.

Q: Can I use a combination of these solutions to bypass tunnelling?

A: Yes, you can use a combination of these solutions to bypass tunnelling. For example, you can use a local DNS server and a reverse proxy with a local IP address to bypass tunnelling. Make sure to configure each solution correctly to ensure that they work together seamlessly.

Q: How do I troubleshoot issues with bypassing tunnelling?

A: If you're experiencing issues with bypassing tunnelling, make sure to check your DNS server and VPN configurations to ensure that they're correctly configured. You can also use tools like dig and nslookup to troubleshoot DNS issues, and tcpdump to troubleshoot VPN issues.

Q: Can I use a cloud-based DNS service to bypass tunnelling?

A: Yes, you can use a cloud-based DNS service to bypass tunnelling. Cloud-based DNS services like Google Cloud DNS and Amazon Route 53 can help you resolve domain names to IP addresses of your local services, bypassing the need for a local DNS server.

Q: Are there any limitations to bypassing tunnelling?

A: Yes, there are limitations to bypassing tunnelling. For example, if you're using a VPN with a local IP address, you may be limited to accessing your local services from within the VPN network. Additionally, if you're using a cloud-based DNS service, you may be limited to resolving domain names to IP addresses of your local services, rather than accessing them directly. Make sure to understand the limitations of each solution before implementing it.
