I try to tunnel SMB and AFP services through SSH to acces my NAS shares on my machine. I already do it successfully with my ReadyNAS using the following command line (ran as my user on my mac) :

ssh -Nf -p 22 -c 3des-cbc USER@SERVER -L 8888/127.0.0.1/548 -L 9999/127.0.0.1/139

but I cannot reproduce the same with the Synology NAS. Connecting using this command gives me the following error :

channel 4: open failed: administratively prohibited: open failed

I also tried with a windows client (used bitvise tunneler): it works with the ReadyNAS but not the Synology and get the following error msg :

server denied request for client-side server-2-client forwarding on 127.0.0.1:139

I modified /etc/ssh/sshd_config :

MaxSessions 10
PasswordAuthentication yes
PermitEmptyPasswords no
AllowTcpForwarding yes
GatewayPorts yes
PermitTunnel yes

Is there any way to make it work ? I must add that I can successfully connect via SSH to the NAS so I donnot think this is a firewall issue between the Synology and my computer.

Thanks for you answers
