Is it possible to have Windows 2003 RAS server translate my internal IIS FTP
server's packets and change the IP address transmitted to reflect the
external one that I have open ports too?

Sure, assuming you use NAT and have two NICs.

Thanks for the reply Bob,

The RAS is setup with two NICs; one to the Internet and one configured to the internal network. Where would I look for this option in the RAS snap in to configure? I've noticed that the packets being transmited from my server to the client and it's using the internal IP address.

ftp ftp.domain.com
Connected to ftp.domain.com (external ip).
220 Microsoft FTP Service
Name (ftp.domain.com:User): username
331 Password required for username.
Password:
230 User upload logged in.
Remote system type is Windows_NT.
ftp> passive
Passive mode off.
ftp> ls
227 Entering Passive Mode (192,168,100,104,19,145).

At this point the connection hangs not because port 5009 is mapped through the RAS but because the ftp client can't find an answer on port 192.168.100.104 cause that is the server's internal network.

Thank you for the reply Robert but I have gotten all other ports and services routing through the RRAS server fine but IIS FTP's packets are being sent to the client with the internal IP address as the returning. Is it even possible for RRAS to rewrite that FTP packet and place the external IP addresst that the RRAS has for that internal/external IP port setup in it's service tab? Also what is this type of operation called so that if RRAS can't do this kind of adjustment I can find a device that can?

Thanks, Nathaniel
