* At least __three__ physical network interfaces on your pfSense server
* The MAC address of your Residential Gateway
* Local or console access to pfSense
* pfSense 2.4.4 _(confirmed working in 2.4.3 too, other versions should work but YMMV)_
* pfSense 2.4.5 _(If you are running pfSense 2.4.4 please see instruction in the [Before-pfSense-2.4.5](https://github.com/MonkWho/pfatt/blob/Before-pfSense-2.4.5/README.md))_
If you only have two NICs, you can buy this cheap USB 100Mbps NIC [from Amazon](https://www.amazon.com/gp/product/B00007IFED) as your third. It has the Asix AX88772 chipset, which is supported in FreeBSD with the [axe](https://www.freebsd.org/cgi/man.cgi?query=axe&sektion=4) driver. I've confirmed it works in my setup. The driver was already loaded and I didn't have to install or configure anything to get it working. Also, don't worry about the poor performance of USB or 100Mbps NICs. This third NIC will only send/recieve a few packets periodicaly to authenticate your Router Gateway. The rest of your traffic will utilize your other (and much faster) NICs.
## Install
1. Copy the `bin/ng_etf.ko` amd64 kernel module to `/boot/kernel` on your pfSense box because it isn't included is pfSense prior to 2.4.5 (_if you are running pfSense 2.4.5 please see instruction in the [master branch](https://github.com/MonkWho/pfatt/blob/master/README.md)_):
a) Use the pre-compiled kernel module from me, a random internet stranger:
```
scp bin/ng_etf.ko root@pfsense:/boot/kernel/
ssh root@pfsense chmod 555 /boot/kernel/ng_etf.ko
```
**NOTE:** The `ng_etf.ko` in this repo was compiled for amd64 from the FreeBSD 11.2 release source code. It may or may not work on other versions of pfSense depending if there have been [significant changes](https://github.com/freebsd/freebsd/commits/master/sys/netgraph/ng_etf.c).
b) Or you, a responsible sysadmin, can compile the module yourself from another, trusted FreeBSD machine. _You cannot build packages directly on pfSense._ Your FreeBSD version should match that of your pfSense version. (Example: pfSense 2.4.4 = FreeBSD 11.2)
```
# from a FreeBSD machine (not pfSense!)
fetch ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/11.2-RELEASE/src.txz
tar -C / -zxvf src.txz
cd /usr/src/sys/modules/netgraph
make
scp etf/ng_etf.ko root@pfsense:/boot/kernel/
ssh root@pfsense chmod 555 /boot/kernel/ng_etf.ko
```
**NOTE:** You'll need to tweak your compiler parameters if you need to build for another architecture, like ARM.
2. Edit the following configuration variables in `bin/pfatt.sh` as noted below. `$RG_ETHER_ADDR` should match the MAC address of your Residential Gateway. AT&T will only grant a DHCP lease to the MAC they assigned your device. In my environment, it's:

5. Prepare for console access.
6. Reboot.
7. pfSense will detect new interfaces on bootup. Follow the prompts on the console to configure `ngeth0` as your pfSense WAN. Your LAN interface should not normally change. However, if you moved or re-purposed your LAN interface for this setup, you'll need to re-apply any existing configuration (like your VLANs) to your new LAN interface. pfSense does not need to manage `$RG_IF` or `$ONT_IF`. I would advise not enabling those interfaces in pfSense as it can cause problems with the netgraph.
8. In the webConfigurator, configure the WAN interface (`ngeth0`) to DHCP using the MAC address of your Residential Gateway.

If everything is setup correctly, netgraph should be bridging EAP traffic between the ONT and RG, tagging the WAN traffic with VLAN0, and your WAN interface configured with an IPv4 address via DHCP.

Once your netgraph setup is in place and working, there aren't any netgraph changes required to the setup to get IPv6 working. These instructions can also be followed with a different bypass method other than the netgraph method. Big thanks to @pyrodex1980's [post](http://www.dslreports.com/forum/r32118263-) on DSLReports for sharing your notes.
This setup assumes you have a fairly recent version of pfSense. I'm using 2.4.4.
