Hi all, Have written a small client app to transfer a text file to a server running on another pc in the LAN... This works beautifully!! Not that difficult to do over a LAN right ? So My concerns deal with WAN communication... - What security issues must i cater for (like firewalls) and how do I do that ? - If my server app will be running in another building on its own LAN of 5 pcs, how do i differentiate it from the other 4 pcs... In my LAN all i had to do was specify the IP address and port and didnt have to worry about firewalls, user authentication or subnet-masks... Do I have to now with the WAN? Thanks Chris
