I have got a ASA 5510 running 7.2.1.
The outside interface recieves the IP address over pppoe. Normaly you don't need to configure a fix IP with pppoe, but for any reason I don't recieve an IP address until I hardcode it on the ASA. Then when I reboot the ASA the IP address of the outside interface is lost.Further, I'm not able to change the subnetmask, it changes always to a host subnetmask. Has someone already made the same experience? See below the configuration of the outside interface and the pppoe statements.
pppoe client vpdn group any
ip address XXX.XXX.XXX.XXX 255.255.255.255 pppoe setroute
vpdn group any request dialout pppoe
