Hi, good morning,

in office, I have two computers (OPC1, OPC2) with ftp servers
installed . different domain,
OPC1's ftp port is open to outside, and I can access it from home,
OPC2's ftp port is not open to outside, but open to OPC1. I cannot
access OPC2 from home, but OPC1 can access it

so, Just wonder, how to set up a coneection from home to OPC2 via OPC1,
if possible

thanks a lot

No it is not possible, in the way you are asking it.Each one must be handled
separately.

You could create a Virtual Folder on OPC1 that references a location on
OPC2, but that is not the same as what you are asking and the permissions
might be a mess to over come since they aren't in the same domain.
 
Well the easy way would be to set up a port mapper.

1. install whatever port mapping package you chose on OPC1.
2. Map some port port (ex. 8021) to forward to port 21 on OPC2.
3. Make sure that which ever port you chose (ex. 8021) can be accessed by
the internet (routre & firewalls)

I belive that this solution should work for you. However, if you are using a
router that allows port forwarding, I would just forward lets say incomming
port 8021 to forward to port OPC2 and set the ftp server daemon to listen on
port 8021 in addition or instead of port 21.

another option, depending on your OS (ex. XP pro) allows remote desktops.
1. allow access to the rdp service (if applicable) on opc1
2. from home open an rdp session to opc1
3. map a local drive from the home pc to opc1
4. run the ftp software with the rdp client and transfer using the mapped
local drive

it would help to know more about your situation.

cheers,
James
