Hi, below is a description of my network:
I have several office units in a business center, each office unit has its own public IP address, Proxy Server, etc. For example office unit A have a public address of 123.123.123.123 and LAN address of 192.168.1.0/24 and office unit B have a public address of 234.234.234.234 and LAN address of 192.168.2.0/24. In each unit, the LAN is connect to a Proxy Server and then to ADSL modem and to the Internet.
Now my problem is I can transfer file from one of the machine in office unit A to another user that login to PSI from the Proxy Server of office unit B, but not to any machine in LAN of office unit B. I did a port forwarding in the ADSL modem, and already open the port in the firewall in Proxy Server also.
Anyway have any idea about this problem?
