slackware怎样改防火墙规则

我的samba总是无法正常工作，能启动，却看不到局域网上的机器，而相同配置的fedora却可以。我怀疑是slackware的防火墙做的怪，但不知道在哪个文件里改防火墙规则

我的smb.conf：
[global]
workgroup = MYGROUP
server string = Samba Server
load printers = yes
log file = /var/log/samba.%m
max log size = 50
security = user
ssl CA certDir = /etc/ssl/certs
socket options = TCP_NODELAY
dns proxy = no
[homes]
comment = Home Directories
browseable = no
writable = yes
[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
guest ok = no
writable = no
printable = yes
[public]
comment = Public Stuff
path = /home/myhome/samba
public = yes
writable = yes
printable = no
write list = @staff

看来格格物先生也有IPTABLE的烦恼啊。。。。下载个GUARDDOG吧（我有在SIR里POST过）， 它是IPTABLE－BASED的GNU软件。。。调配容易， 我想应该是SMB的PROTOCOL被BLOCK了。。。。你到那GUARDDOG里去调回来就行了，我有你相同的经历。

好，谢谢茜如和小劲鸭
