if i understand the issue correctly, the host tries to access the ftp serve 192.168.200.200 itself has ip under 192.168.200.x.
so if the other end device can nat/pat the ftp server ip from 192.168.200.200 to 192.168.201.200; whereas the host is also natted to something else.
i guess this is pretty complicated to setup and troubleshoot. the simple solution is to re-configure the ip scheme.
