Gateway README
|
|
==============
|
|
|
|
Under the heading of Gateway are a number of services that provide dhcp addresses and NAT to the lan
|
|
and filter wan access both in terms of content and bandwidth.
|
|
|
|
LAN
|
|
---
|
|
|
|
The LAN is managed by the dhcpd service and by iptables. The configuration of iptables is complicated
|
|
and works as follows:
|
|
|
|
/etc/systemd/system/iptables.service calls
|
|
/etc/sysconfig/iptables-config which calls
|
|
/usr/bin/xs-gen-iptables
|
|
and saves the resultant configuration to /etc/sysconfig/iptables
|
|
it then supplies additional rules to iptables
|
|
|
|
As of March 2014 the following files are obsolete
|
|
|
|
/etc/sysconfig/olpc-scripts/iptables-xs
|
|
|
|
/etc/sysconfig/olpc-scripts/ip6tables-xs
|
|
|
|
Filters
|
|
-------
|
|
|
|
Content is filtered by squid and dansguardian and there are ansible variables that control them.
|
|
|
|
There is a white list file, sites.whitelist.txt. URL patterns not in this file will not be accessible.
|
|
|
|
An additional rule to block https has been added to iptables, also controlled by an ansible variable.
|
|
|
|
**N.B. https blocking and whitelist checking are disabled by default**
|
|
|
|
To enable whitelist checking and/or https blocking edit
|
|
|
|
#Gateway Filters
|
|
gw_squid_whitelist: False
|
|
gw_block_https: False
|
|
|
|
changing False to True where appropriate and then run runtags facts, gateway
|
|
|
|
Bandwidth is filtered by wondershaper.
