This is wrong, you're revriting outgoing packets to 10.0.0.1.
Just remove these 2 lines.

You may want to change this to:
map pppoe0 10.0.0.0/24 -> 0.0.0.0/32 proxy port ftp ftp/tcp mssclamp 1492
map pppoe0 10.0.0.0/24 -> 0.0.0.0/32 portmap tcp/udp 10000:40000 mssclamp 1492
map pppoe0 10.0.0.0/24 -> 0.0.0.0/32

to work around potential MTU problems.
