 - (Optional) Setup a DNS server, like Unbound.
 - **TODO** Multicast routing.
 
-## Notes
-
-1. For high-performance routing:
-   1. Disabling dynamic frequency and voltage scaling (Intel SpeedStep).
-   2. Disabling multithreading (Intel Hyper-Threading).
-2. Enable IPv4 and IPv6 forwarding in `/etc/sysctl.conf`:
-   1. `net.ipv4.ip_forward=1`
-   2. `net.ipv6.conf.all.forwarding=1`
-3. Configure the firewall for forwarding traffic.
-   1. Configure NAT.
-   2. Setup bogon and RFC 1918 filtering.
-   3. Verify source for stub networks.
-4. Setup DHCP servers for IPv4 and IPv6 (unless using IPv6 SLAAC).
-5. Setup a DNS server.
-6. Setup other servers, like NTP.
