Purpose

Our new shiny router. It's an Alix 2D3 low-power computer, with a 4GB Compact Flash card, running stock Debian Squeeze.

Name

Named after Alonzo Church.

Don't forget to push config changes to Github and (if relevant) update the Logbook.

Firewall/NAT

Set up very simply to iptables-restore /etc/firewall.conf on networking start. To add a new rule, change /etc/firewall.conf and:

iptables-restore < /etc/firewall.conf

Traffic Shaping

We're using a relatively simple traffic-shaping scheme to manage upload bandwidth. Traffic is tagged using fwmark into one of six priority classes in the "shaper" chain in /etc/firewall.conf.

/etc/network/if-up.d/traffic-shaping then configures the traffic shaping (you shouldn't need to touch this and you should tell Russ if you do).

Could this be published on the wiki, as only a limited number of people have access to Church? Robert 13:19, 24 April 2011 (UTC)
- I've put the firewall.conf on Git. The priorities are 20 (highest)-26 (lowest). Ms7821 01:46, 25 April 2011 (UTC)

Access

We like stable internet, so we're not going to hand out accounts willy-nilly. If you need a port mapped, ask one of these people:

If you want to do something more fancy, we'll probably give you access as long as you let us know first :).
