Here's async log output from alias enabled ppp, while ftp was retransmitting
the PORT command packet:
Async: 7e 3d c0 00 00 9d 21 45 00 00 38 13 42 00 00 ff
^^
Async: 01 e3 a7 cf ca 49 aa d0 17 db 4e 03 03 a2 f8 00
Async: 00 00 00 45 00 00 39 a4 4e 00 00 2e 11 79 35 d0
^^
Async: 17 db 4e cf ca 49 aa 04 00 00 35 00 25 00 00 e3
Async: 69 7e
If looked like somehow the first ip frame was overwritten by a second ip
