Problema con puerto 80
Hola, tengo un router cisco 677, y al intentar hacer un servidor WEB o FTP, no lo logro ya que el puerto 80 y el 21 estan cerrados. Hay alguna forma de abrirlos por software??o el router me esta bloqueando. Cuando intento por modem todo bien. Anda. Pero Quiero por Router ADSL!Si alguien sabe le agradezco de antemano su ayuda.

Te lo paso en Ingles:
Disanbling NAT
If you have a public address on the inside network, and you want the inside hosts to go out to the outside without translation, you can disable NAT. You would also need to change the static command. Using the example above, the nat command would be changed to:
nat (inside) 0 175.1.1.0 255.255.255.0
or if you are using ACLs in PIX software versions 5.0.1 and later:
access-list 103 permit ip 175.1.1.0 255.255.255.0
any
nat (inside) 0 access-list 103
This command disables NAT for the 175.1.1.0 network. The static command for the web server would be changed to:
static (inside, outside) 175.1.1.254 175.1.1.254
The following command defines the conduit for the web server:
Conduit permit tcp host 175.1.1.254 eq www any
or if you are using ACLs in PIX software versions 5.0.1 and later:
Access-list 102 permit tcp any host 175.1.1.254 eq
www
access-group 102 in interface outside
Note that the difference between using nat 0 with specifying network/mask as opposed to using an ACL that uses a network/mask that permits initiation of connections from inside only. The use of ACLs permits initiation of connections by inbound or outbound traffic. The PIX interfaces should be in different subnets to avoid reachability issues.
Pero dejas los puertos abiertos y tienes que activar los servidores o el personal se te colara hasta la cocina.
Puntuame y suerte
