Hello All,
I have a strange problem regarding samba 3.0.37
I have samba server installed in the local network behind NAT, the
router iptables are configured as follows:
#samba
$IPT -t nat -A PREROUTING -i $INET_IFACE -p udp -d $INET_IP -m multiport --dports 137,138 -j DNAT --to-destination $FILESERV
$IPT -t nat -A PREROUTING -i $INET_IFACE -p tcp -d $INET_IP -m multiport --dports 139,145 -j DNAT --to-destination $FILESERV
#samba
$IPT -A FORWARD -p udp -m state --state NEW -i $INET_IFACE -d $FILESERV -m multiport --dports 137,138 -j ACCEPT
$IPT -A FORWARD -p tcp -m state --state NEW -i $INET_IFACE -d $FILESERV -m multiport --dports 139,145 -j ACCEPT
The samba server is working fine and both smbd and nmbd are started. I
have no problems accessing samba shares from local network using \\IP or
\\HOSTNAME
But when I try to access samba from outside of my network I can only
use \\IP, any attempt to use \\HOSTNAME results in "Windows couldn't
find HOSTNAME..." message, though HOSTNAME on windows machine is resolved
correctly.
I thought it might be related to "interfaces" option, so I added
router address into it but still cannot access samba by HOSTNAME from
outside of the network. I all so sure that the problem doesn't relate to
one particular windows setup since I can reproduce the problem on all
windows machines outside local network.
From samba log files it looks like there is no connection comes when
\\HOSTNAME is used on windows computers.
I would appreciate if someone could shed a light upon the problem.
Thanks in advance.
