This configuration file has several irrelevant settings.
Try the one below, it's from here:
/usr/share/examples/ppp/ppp.conf.sample
I just added "set authname" & "set authkey",
changed the NIC's name and removed the service name.

pppoe:
 set authname "your_username"
 set authkey "your_password"
 set device PPPoE:rl0
 enable lqr echo
 set cd 5
 set dial
 set login
 set redial 0 0

This has nothing to do with modem bridging mode.
This bridges your two ethernet segments. Disable it if
that's not what you want.

^^^^^^^^^^^^^^^^^^
Zero octets in and zero octets out. Is your modem in bridging mode?
It may be called rfc1483. Enable it.

check what goes on with tcpdump:
root:0:/# tcpdump -nli rl0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on rl0, link-type EN10MB (Ethernet), capture size 96 bytes
14:34:54.863275 PPPoE PADI [Host-Uniq 0xC0656EC3] [Service-Name]
14:34:56.862997 PPPoE PADI [Host-Uniq 0xC0656EC3] [Service-Name]
14:34:59.969272 PPPoE PADI [Host-Uniq 0xC00CFAC3] [Service-Name]

This is not what you should see, you should see PADO and the rest.
If that's what you see, your modem is probably not in bridging mode.

Hope this helps
