bridge/forwarder IP for FTP

Hi, First let me explain the network 

Site A

IP - 192.168.0.1 - 192.168.0.100

Subnet - 255.255.255.0

Site B

IP - 192.168.1.1 - 192.168.1.100

Subnet - 255.255.255.0

Connection: IPSec LAN-LAN 

Device : TL-ER6120

Works fine I can ping devices across subnet without any issues. Can ping/transfer files from PC-PC

The actual issue is that there are few legacy IP cameras that only scans for storage FTP locations in the current subnet to store the recordings. In my case Site, A has an FTP server that can store the recordings. Site B has a couple of those cameras. But when the scan runs there are no such FTP servers running in that subnet. Ideally, the camera scans from 192.168.1.1 - 192.168.1.100. then gives up stating no storage server

Is there any way this could be solved by sacrificing an IP such as 192.168.1.100 and make a static route to my FTP server. So that device, when it scans, shows FTP in 192.168.1.100 but the actual FTP server is running in Site A with some IP.

or is there a way to solve this issue by adding some sort of bridge/forwarder in FTP.
