I know I can set up an SSH tunnel and proxy my traffic through the

My question is, can I pass NFS or SaMBa traffic via an SSH tunnel as
well?  Performance via the tunnel is not a priority.


Samba yes, port 139(*), the host you are tunneling from will need
to be allowed to access the share.  NFS, don't know.

(*) Can be tunnelled from a Windows machine if you:
1. Install a loopback interface on 10.0.0.x (**)
2. Do the forwarding from 10.0.0.x:139 to the server port 139
3. Point windows at the share on 10.0.0.x:139
(**) Apparently there's some issue with 127.0.0.x loopbacks,
but I've never investigated.

Maybe I should have included a wonderful ASCII diagram so you can see how everything is laid out as the example you provided I think only allows between the two ssh endpoints.

Here is my pitiful ascii diagram:
                                    Private (10.x.x.x/8 addressing)
                                   |
                v-public address   v        /--(smb fileservers)
(HostA)------(FW)--internet---(FW)---------------(HostB)
       ^                     ^-public address
       |
(private 172.16.x.x/20 addressing) I need (want?) host A to be able mount filesystems from any of the smb fileservers. Host B has both NFS and Samba loaded and can mount smb filesystems from the smb fileservers today.

Also Host B's address space is in the 10 net, obviously I can choose another address range for a loopback, but I've never seen anything other than 127.0.0.1 as a loopback on a unix machine and changing it will surely break something. Can I create loopback1? I've never tried....

The SSH tunnel is between the two unix machines (Host A and Host B) only with the windoZe machine behind the unix machine terminating the ssh tunnel.

I have found sshfs and I'm in the process of reviewing it to see if it can do what I want.
