trouble connecting to Samba outside firewall

Posted on 2012-08-22

I have a samba mountpoint configured on my Linux Slackware webserver. people within the LAN (192.168.2.) can connect w/o problem. I cannot connect to it from outside. I'm sure it's not a problem on the client end since I can make similar connections to other such servers. It must either be a firewall problem or some kind of issue with the ISP (which is AT&T). I have the following ports open on the modem/router and forwarded to the Linux host:

TCP 139,443
UDP 137-138

Perhaps that is not correct? I have no firewall configured on the Linux host.

Slacware version 13.37.0, kernel version, smbd version  1.6g

Help would be GREATLY appreciated

    Do #nmap from remote host to slackware server. This makes sure SMB ports are open or not.

    #nmap slackware.web.server

    If the ports are open, you can in the results.
    ports : 139 and 445 should be open in order to work SMB correctly.

    Here what I've got:

    Not shown: 994 filtered ports
    22/tcp   open   ssh
    25/tcp   open   smtp
    80/tcp   open   http
    139/tcp  open   netbios-ssn
    443/tcp  closed https
    3389/tcp open   ms-term-serv

    I'll try opening 445 this evening and see if that helps.

    forwarding port 445 did the trick! Thanks.
