SMB and CIFS are not two different things.
They are the same thing, for all intensive purposes.
CIFS is just the newer version of SMB.
After a certain point SMB was renamed to CIFS.
I handle SMB all day long at work.
Admittedly SMB is much older and is mostly 95/98 compatible.
Place the NAS in CIFS mode and you should be able to mount with the amiga copy of smb.
You can run into issues though if you choose the wrong mode.
You do NOT want NTLM v2. This requires SMB 3.something to work. Stick with NTLM v1.
"User" or "share" mode should be ok.
Do not use anything to do with servers like NT or AD modes.
If you can post a pic of the CIFS settings screen I will have a look.
