Pessoal blz,
colcoquei um firewall para rodar mas n�o sei porque cargas d'�gua n�o ta
funcionando direito como deveria
coloquei as op��es no 
rc.conf:
gateway_enable="YES"
natd_enable="YES"
natd_flags="-l -f /etc/natd.conf"
natd_interface="tun0"
firewall_enable="YES"            # Set to YES to enable firewall
functionality
firewall_type="client"           # Firewall type (see /etc/rc.firewall)


no arquivo natd.conf:
interface tun0
dynamic yes
same_ports yes
use_sockets yes

e alterei o rc.firewall, por�m estou com a seguinte tabela:
00050 1654 718264 divert 8668 ip from any to any via tun0
00100 8832 469980 allow ip from any to any via lo0
00200    0      0 deny ip from any to 127.0.0.0/8
00300    0      0 deny ip from 127.0.0.0/8 to any
00400    0      0 allow ip from 192.168.0.2 to 192.168.0.0/24
00500    0      0 allow ip from 192.168.0.2 to any via tun0
00600    0      0 allow tcp from 192.168.0.2 to any established
00700    0      0 allow ip from 192.168.0.2 to any frag
00800    0      0 allow tcp from any to 192.168.0.2 25 setup
00900    0      0 allow tcp from 192.168.0.2 to any setup
01000    0      0 deny tcp from any to 192.168.0.2 setup
01100    0      0 allow udp from 192.168.0.2 to any 53 keep-state
01200    0      0 allow udp from 192.168.0.2 to any 123 keep-state
65535 1591 714146 allow ip from any to any

Porem tentei abrir uma conexao ssh e consegui enquanto que n�o deveria
ser poss�vel isso algu�m poderia me indicar algum poss�vel erro ou algo
que eu tenha me esquecido na configura��o, sempre lembrando esse
firewall esta em uma m�quina com conex�o discada.
