Yes, and it has nothing whatsoever to do with your AXIP tunnel.

In mbx_getname() the callsign is stripped of its SSID if the protocol
of the incoming connection to the mailbox is AX.25 or Net/Rom.  It has
been this way since the beginning of time so that users who use the
mailbox gateway functions will go out with a "-15" SSID.  Unfortunately,
this *does* get in the way of trying to setup different sets of FTPuser
privileges using the same callsign when the protocol of the incoming
connection to the mailbox is AX.25 or Net/Rom.

In the past, we have solved the problem of PBBSs and users having
the same callsign by choosing another callsign entirely for the
connecting PBBS, or the user, whichever is your preference, so that
a separate entry may be put into the FTPusers file.
