Dear all,
The idea is to share it over a local area network.
This LAN has a wins server.
my server has a jail in which samba resides.
In order for the LAN to be serviced by my jailed samba I have NATED and
RDRed the required packets
In order for the LAN to browse the network NETBIOS seems to be a problem.
AFAIK when one sends a netBIOS packet an ip is embedded and the response is
sent to that ip. NAT only redirects the packet to he appropriate network,
but apparently the packet needs to be altered too in order for a response to
be sent.
I hope this information was sufficient
<snip>
smb_jail_ip="10.0.0.3"
int_ip="172.20.25.177"
samba_UDP_ports = "{netbios-ns, netbios-dgm}"
samba_TCP_ports = "{microsoft-ds, netbios-ssn}"
#smb
nat on $int_if from $smb_jail_ip to $int_if:network ->$int_ip
rdr on $int_if proto TCP from any to $int_ip port $samba_TCP_ports ->
$smb_jail_ip
rdr on $int_if proto UDP from any to $int_if:broadcast port $samba_UDP_ports
-> $smb_jail_ip
rdr on $int_if proto UDP from any to $int_ip port $samba_UDP_ports ->
$smb_jail_ip
pass in quick on $int_if all
pass out quick on $int_if all
