EdgeRouter Lite DN42 config example
This is the config I (Felicitus) am running on an Ubiquiti EdgeRouter Lite (AS76197).
Features
- dn42 DNS
- "classic" OpenVPN P2P (including the common "comp-lzo" option)
- BGP
- Some traffic-shaping rules for my very slow 3mbit DSL uplink
- 2 internal: One DN42 network (172.22.117.128/25 for me and my servers as well as a NAT 192.168.42.10/24 for my parents, so that they're save from dn42 - that network is NOT announced to dn42).
- Firewall to protect my NAS server and monitoring
Upcoming
- AICCU integration (SIXXS), probably not possible with the config, so
apt-get install aiccushould do the trick - dn42 IPv6 routing (probably)
Ask me if you want to know if I have implemented those items already.
