I assume you use the pppoe like described in the installation guide

The message "Couldn't increase MTU or MRU to 1500" has no

There seems to be a problem with the login sequence

comment them all out. (it works here without all of them)

1. check your shorewall setting ppp0 is external interface ( not eth0)
add the line debug 7 in your dsl pppd options
now you will have additional messages:
Like:
The messages are shortened to stay readable
sent [LCP ConfReq id=0x1 <magic 0x32bxxxxx>]
rcvd [LCP ConfReq id=0xb3 <mru 1492> <auth pap> <magic
0xc04yyyyy>] 00 ...
sent [LCP ConfAck id=0xb3 <mru 1492> <auth pap> <magic
0xc04yyyyy>]
rcvd [LCP ConfAck id=0x1 <magic 0x32bxxxxx>] 00 00 00 .....
sent [LCP EchoReq id=0x0 magic=0x32xxxxx]
--------Now follows the authentication request
sent [PAP AuthReq id=0x1
user="[EMAIL PROTECTED]"password=<hidden>]
rcvd [LCP EchoRep id=0x0 magic=0xc04yyyyyy] 00 00 00 00 00 00
00 00 00 00 00 00
rcvd [PAP AuthAck id=0x1 ""] 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 0
--- OK your authentication is succesfull notice the change of the
protocoll
what follows now is the debate about what ip number you will get.
sent [IPCP ConfReq id=0x1 <addr 0.0.0.0>]
rcvd [IPCP ConfReq id=0xf3 <addr 11.22.33.44>] 00 00 00 00 00
00 00 00 00 00
sent [IPCP ConfAck id=0xf3 <addr 11.22.33.44>
OK you take this IP ;)
Now the same happens for the peers IP
]
I hope this will help you to find the cause ,
Some frequent problems are:
1. including special characters in name and or password and not
putting the name and or password in Quotes ("")
2. wrong external interface eth0 and not ppp0 as it should be
3. automatically dialing of pppd to serial with a file in /etc/ppp see
manual.
