First configure ur PPPoE on the outside interface:
vpdn username password
vpdn enable outside
Then set:
ip address outside pppoe
& chk whether things work properly.
Else set the modem in PPPoE mode to initiate the PPPoE session & u assign a pvt address to ur f/w's outside interface & configure the NAT'ing & Port forwarding of ur modem's public IP with the f/w's pvt IP address.[/b]
from
Cisco PIX command reference:
enable if_name: Enable the VPDN function on a PIX Firewall interface. Specifies the
interface in if_name where L2TP or PPTP traffic is received.Only
inbound connections are supported.
Then this is not necessary
I know exactly which commands configure the pix for dialing pppoe:
vpdn group pppoe-
adsl request dialout pppoe
vpdn group pppoe-adsl localname my_username
vpdn group pppoe-adsl ppp authentication pap
vpdn username my_username password my_password
ip address outside pppoe setroute
It seems you didn't understand exatly the problem
My PIX dial the pppoe connection correctly, then authenticate correctly and then does not receive the ip address from the DSLAM
Neither works with the fixed ip on the outside interface
ip address outside 59.xxx.xxx.xxx 255.255.255.255 pppoe
the problem is this line
PPP - dev 1, xmit data pkt, but ipcp protocol is not up
after this the DSLAM ask the PIX to terminate the connection
