This package allows you to connect to your ISP via additional virtual circuits (ATM PVC’s). For some (older) setup’s multiple virtual circuits are used to ofer Triple Play services where for each service (e.g High speed Internet, Broadband TV and Voice) a virtual circuit is used. More modern networks often used one converged IP network with only one virtual circuits.

I used Freetz-1.2 for a FritzBox 7170.
Follow the directions from the Wiki After the following step you can configure the packages you want to have included in your image.
make menuconfig
Package selection ---> Testing ---> [*] br2684ctl (binary only)
For Client DHCP you can additionally enable the following option. You can also add a script (default.script) to the image at compile time (see below for details).
Advanced options ---> BusyBox options ---> [*] udhcpc
There is no GUI interface for br2684ctl. There is only one executable with a number of mandatory and optional parameters.
br2684ctl [-c n -e 0|1 -b -s buf_size [-q qos] -a [itf.]vpi.vci ]
ATM PVC number, VPI and VCI. -a [itf.]vpi.vci
BR2684 interface number such as nas0, nas1,…, where the number is n (e.g. nas0 is -c 0). This is a mandatory parameter. -c n
Encapsulation method. 0=LLC, 1=VC mux. default is 0, LLC This is a mandatory parameter. -e 0|1
Running background. Default (parameter ommited) is foreground. -b
Send buffer size. Default is 8192. -s buf_size
Optionally there are QoS parameters for traffic shaping, and cell rate
limiting.
-q
Example: Creating ATM PvC 0/32 in the background with interface name nas0 using LLC encapsulation.
br2684ctl -b -e 0 -c 0 -a 0.32
br2684ctl -e 0 -c 0 -q ubr,aal5:max_pcr=5Mbps,min_pcr=320kbps,max_sdu=1524 -a 0.32
After the interface is created you can see it with the following command:
ifconfig -a
or
ifconfig nas0
Some details can be viewed at:
cd /proc/net/atm/
ls -la
cat <file>
The udhcpc package, part of BusyBox, is a DHCP Client program, that obtains configuration parameters from a DHCP Server. Udhcpc configures enviroment variables with the parameter values obtained from the DHCP Server. A configure script (e.g. a shell script) can make use of these variables to configure an interface, DNS servers, NTP Servers, and a lot of other possible information.
Freetz doesn’t have a (default) DHCP configure script. Here an example script to just configure an IP address with broadcast address and subnetmask. To include the script (default.script) at compile time follow the following steps:
cd ~/freetz-x.y/addon/
echo default.script >> static.pkg
mkdir -p default.script/root/etc/dhcp/
vi default.script/root/etc/dhcp/default.script
#!/bin/sh
[ -z "$1" ] && "Error: should be run by udhcpc" && exit 1
case "$1" in
deconfig)
ifconfig $interface 0.0.0.0
# echo interface = $interface
;;
leasefail)
;;
nak)
;;
renew|bound)
ifconfig $interface $ip
broadcast $broadcast
netmask $subnet
# echo interface = $interface
# echo ip address = $ip
# echo subnet = $subnet
# echo netmask = ${subnet:-255.255.255.0}
;;
esac
Enable the interface:
ifconfig nas0 up
Obtain ip configuration info via DHCP:
udhcpc -i nas0 -s /etc/dhcp/default.script
To obtain additional debug information from the udhcpc package you need to enable this, and recompile a new image.
cd ~/freetz-x.y/source/target-mipsel_uClibc-0.9.29/ref-8mb/busybox-1.18.5
vi .config
In the .config file search for CONFIG_UDHCP_DEBUG=0 and change it to:
CONFIG_UDHCP_DEBUG=3
Initiate recompile of the busybox packages during the next make:
cd ~/freetz-1.2/
make busybox-clean
Compile a new image with:
make
After installing the new image on the FritzBox start the DHCP Client with:
udhcpc -i nas0 -s /etc/dhcp/default.script -vvv
the number of v’s determines the detail of debug packages.
