u can check wan ip there, tats ur real ip, and u need to forward ur ftp port to ur pc.

for example, d-link admin page is 192.168.10.1(not sure), login and look for something like "system status" tat shows ur wan & lan status including ips.
den look for "port forwarding", forward 80(or any port used for ftp) to ur pc ip, like 192.168.10.3

den outsider can access ur ftp.

btw, maxonline 1500 uplink limit is 128kbps, which is 128/8=16kB/s.
it means ur fren download speed canot exceed 16kB/s, normally it could be arnd 12-15KB/s, for china, maybe even lower..........
if more than 1 person DL at same time, they share the 15KB/s....so....

so better dun use such method to share ur photo.
if not many, email will do.
if many, try upload to a webserver and let them download or direct transfer using msn or qq or yim etc.....

anyway, up 2 u
