So, your FreeBSD box is within your LAN and have do dial with ADSL at all,
only your router have. Your box have internal LAN's IP 192.168.1.8 and
your router configured to do network address and port translation.
This network configuration is completely different from my one.
I have a modem, not a router.

This is a copy/paste of just 'ifconfig', so you can see all the interfaces:
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::200:21ff:fe82:2503%ed0 prefixlen 64 scopeid 0x1
ether 00:00:21:82:25:03
faith0: flags=8002<BROADCAST,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
inet 127.0.0.1 netmask 0xff000000
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
inet 192.117.108.59 --> 192.117.122.11 netmask 0xffffffff

I don't use ed0 directly, ppp use it for ppp0. ed0 is like /dev/cuaa1
when you have regular modem, 33600bps one for example. I use tun0 that
support TCP/IP and have MTU == 1492. Read RFC 2516 for information about
the maximum MTU that is correct with PPPoE protocol. 1492 is the maximum.
