Hi All,

If I disable the iptables on the server then I can use the command

mount -t cifs //192.168.122.21/sharedata tmpdata -o username=smbuser4,password=1234

If I enable the iptables. However I have use the commands on server

iptables -A INPUT -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT
iptables -A INPUT -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT
iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 139 -j ACCEPT
iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 445 -j ACCEPT

Then I get the error.

mount -t cifs //192.168.122.21/sharedata tmpdata -o username=smbuser4,password=1234
Unable to find suitable address.

Please help.

Have you run tcpdump with the iptables stopped to see what communications are in use.
If I recall right the protocol should be tcp for all ports.
