Please help me ! Samba/netbios do not work until I staticaly open UDP ports above 1024 for new connections!!!
As far as I know SAMBA uses TCP/UDP 137:139 for initiating a new connection Corect me if I'm wrong, SAMBA/netbios never send first packet to a destination port higher than 1024. (in the default install) There are packets sent to a port higher than 1024 but they should be only a reply to a request If I'm right first rule should let them get in. Default policy is DROP 1 iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT 2 iptables -A INPUT -p tcp --dport 137:139 -m state --state NEW -j ACCEPT 3 iptables -A INPUT -p udp --dport 137:139 -m state --state NEW -j ACCEPT 4 iptables -A OUTPUT -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT Is that corect ? Is that enough ? For me it works only if I staticaly open some UDP ports (for new connections) above 1024 like this: 5 iptables -A INPUT -p udp --dport 1024:10000 -m state --state NEW -j ACCEPT I did not changed samba default port In our domain is also a WINDOWS machine as PDC Please help me ?
