🔒 ASUSWRT vs Merlin Firmware

Out of the box, ASUS’s stock firmware is solid, offering:

• AiProtection by Trend Micro
• Adaptive QoS
• VPN client & server
• AiMesh
• Parental controls

But if you flash ASUSWRT-Merlin, you unlock a new level of customization without losing the original UI’s polish. Key benefits include:

✅ Enhanced VPN support (policy-based routing, custom DNS for VPN clients)
✅ AMTM support (Asuswrt-Merlin Terminal Menu for installing scripts)
✅ DNSCrypt / DoH / DoT support
✅ Custom firewall rules via iptables
✅ More control over DHCP, DNS, NTP, and logging
✅ Integration with Entware packages
✅ Dual WAN customization & flexible NAT rules

Merlin is ideal for users who want more control but don’t want to run their own OpenWRT or pfSense box.
