очень прошу прощения, но сам разобраться не смог.
есть CISCO 2811 необходимо через неё настроить публикацию FTP, RDP + настроить VPN.
Читая конфигу и разбираясь что куда я совсем запутался, так вот прошу у сведущих помощи. для начала почему не работает проброс FTP.

banner exec ^CCCCCCCCC
% Password expiration warning.
-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for  one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to
use.

почему пробрасываете 20 порт ? для FTP должен быть 21
PPTP вроде корректно насроен
