[nSLUG] "No route to host" under samba

I was going to suggest trying with just the IP first,

smbclient -L // -N

but now I realize it is presumably trying the correct IP anyway.

If this fails the same way, then my guess is that outweb has a firewall 
dropping incoming connections.

You can check with:
iptables -L, iptables -t nat -L

I don't remember the smb.conf file well enough, but I wouldn't be 
surprised if it can also limit connections in some way as well.

If there are no firewall rules to drop packets, then I would start trying 
to use tcpdump (or ethereal might be easier to use if you're not used to 
tcpdump) to look at what's going on, network wise.
