1 Brief Installation guide for L2TPNS
5 * libcli 1.5.0 or greater
6 You can get it from http://sourceforge.net/projects/libcli.
8 * A kernel with iptables support
10 * If you want to use throttling, you must have a kernel and a tc (iproute) which supports HTB.
20 * make install. This does:
21 * Install the binaries into /usr/bin (l2tpns, cluster_master and nsctl)
22 * Create config dir /etc/l2tpns and create default config files
23 * Ensures that /dev/net/tun exists
25 * Modify config file. You probably need to change most of the config options.
27 * Set up basic firewall rules. This should be done in an init script.
29 iptables -t nat -N l2tpns
30 iptables -t nat -A PREROUTING -j l2tpns
31 iptables -t mangle -N l2tpns
32 iptables -t mangle -A PREROUTING -j l2tpns
34 * Set up walled garden firewall rules. This should be done in an init
35 script. This is not required unless you are using the garden plugin.
37 iptables -t nat -N garden >/dev/null 2>&1
38 iptables -t nat -F garden
39 iptables -t nat -A garden -p tcp -m tcp --dport 25 -j DNAT --to 192.168.1.1
40 iptables -t nat -A garden -p udp -m udp --dport 53 -j DNAT --to 192.168.1.1
41 iptables -t nat -A garden -p tcp -m tcp --dport 53 -j DNAT --to 192.168.1.1
42 iptables -t nat -A garden -p tcp -m tcp --dport 80 -j DNAT --to 192.168.1.1
43 iptables -t nat -A garden -p tcp -m tcp --dport 110 -j DNAT --to 192.168.1.1
44 iptables -t nat -A garden -p tcp -m tcp --dport 443 -j DNAT --to 192.168.1.1
45 iptables -t nat -A garden -p icmp -m icmp --icmp-type echo-request -j DNAT --to 192.168.1.1
46 iptables -t nat -A garden -p icmp -j ACCEPT
47 iptables -t nat -A garden -j DROP
49 * Set up IP address pools in /etc/l2tpns/ip_pool
53 * Run cluster_master on a separate machine
54 * Set the "cluster master" and "bind address" parameters in /etc/l2tpns/l2tpns.cfg
56 * Make l2tpns run on startup
63 This software is quite stable and is being used in a production
64 environment at a quite large ISP. However, you may have problems
65 setting it up, and if so, I would appreciate it if you would file
66 useful bug reports on the Source Forge page:
