Can I use custom DNS rules on my router to dynamically prioritize Smart DNS over VPN for streaming domains?

Can I use custom 축구중계 DNS rules on my router to dynamically prioritize Smart DNS over VPN for streaming domains?

✅ Short Answer: Yes — with the right router firmware and configuration, you can create DNS rules to prioritize Smart DNS for specific domains (like streaming platforms), while using a VPN tunnel for everything else.

This setup is called policy-based DNS routing or domain-based routing, and it gives you full control over which traffic goes where.

???? Concept Breakdown

Goal	Method
Use Smart DNS for streaming sites (e.g., `dazn.com`, `spotvnow.co.kr`)	Route only these domains via custom DNS like ExpressVPN's MediaStreamer
Use VPN for everything else	Set your router's default WAN connection to pass through the VPN tunnel

⚙️ What You Need

Router with advanced firmware like:
- AsusWRT-Merlin
- DD-WRT
- OpenWRT
- pfSense
- Ubiquiti EdgeOS / UniFi Dream Machine
VPN provider that supports Smart DNS:
- ExpressVPN (MediaStreamer)
- NordVPN (SmartPlay DNS)
- Surfshark (Smart DNS)
Ability to edit DNSMasq, iptables, or DNS forwarding rules on the router

✅ Step-by-Step Overview (Example: AsusWRT-Merlin)

1. Set VPN as the 축구중계 Default Route

Configure the VPN client inside the router's firmware.
All outbound traffic will be tunneled through the VPN by default.

2. Define Custom DNSMasq Rules

Add rules to your router’s DNS configuration like:

bash

복사편집

address=/dazn.com/123.456.78.90 address=/espn.com/123.456.78.90

(Replace 123.456.78.90 with your Smart DNS IP from the VPN provider)

This forces those specific domains to resolve through the Smart DNS provider.

3. Bypass VPN for Smart DNS Traffic

Use policy-based routing or firewall rules (iptables) to bypass the VPN for DNS resolution:

bash

복사편집

ip rule add from <SmartDNS_IP> table 100 ip route add default via <WAN_IP> table 100

✅ Result:

dazn.com, espn.com, and other streaming domains resolve via Smart DNS
All other traffic (browser, downloads, private browsing) routes through the encrypted VPN tunnel

???? Advanced Option: 축구중계 Use pfSense or OpenWRT + DNS-over-TLS

On pfSense, use unbound DNS resolver + conditional forwarding
Create DNS override rules for specific domains
Use multiple WAN interfaces: one for VPN, one for Smart DNS
Add firewall rules to route based on FQDN (Fully Qualified Domain Name)

???? Bonus: Failover Logic

Add scripts to detect when VPN drops, and auto-switch all traffic to Smart DNS as backup
Some routers allow event triggers to re-route based on VPN connectivity

???? Real Use Case

Example:
You're streaming a Champions League match on DAZN using Smart DNS, but simultaneously want your browser and email routed through a VPN.
This setup ensures:

✅ Low-latency HD stream with no VPN detection issues
✅ Privacy & encryption for all sensitive activities
✅ Automated behavior that requires no manual switching mid-match

⚠️ Watch Out For:

ISP DNS hijacking: make sure router blocks external DNS leaks
DNS caching issues: flush DNS regularly on device
VPN DNS overrides: some VPNs force DNS redirection; disable this if needed

Q1: How can I monitor in real-time which domains are routing through Smart DNS vs VPN on my home network?

Q2: What’s the best router firmware for managing Smart DNS/VPN split-routing with a GUI instead of command line?

Q3: Can I schedule automatic routing rules so that streaming traffic uses Smart DNS only during live match times?
