samba+iptables

[humberto@coltec.ufmg.br]

Hello Everybody!

I utilize iptables 1.2.2 running in a kernel 2.4.5.
All services (ftp, http, smtp, ssh etc.) are ok because my NAT linux box 
is accepting all conections for INPUT, OUTPUT and FORWARD.
But after make a NAT in my lab my worktstations with windows NT 4.0 can't
reach the samba server.
Anybody knows howto configurate iptables to recover the connection to my
samba server? 


--Thanks
