Access LAN network by outside ip address from LAN, loopback

[digbym650]

Hello,

 I have a number of computers connected to a Cisco router, which in turn is connected

to an ISP via WAN.  I was wondering if I can send data, e.g FTP to my static outside ip address

from my LAN, or is it only possible for outside networks to access my network via my outside

ip address. i.e. can I test my outside ip address services from my LAN using the outside ip

address. Does loopback do this?

Thankyou

You can use NAT, i.e. your inside ips to be NATed to outside Internet (public) IP.
