Enable Rsync from outside of LAN

Hi,
The /etc/rsyncd.conf contains a hard-coded line for only allowing connections from LAN, e.g:
hosts allow = 192.168.0.0/24,127.0.0.1
I'm aware of the security implications of loosening this, but I have a NAS connected through LAN-to-LAN VPN and would like to enable Rsync from my local LAN to the remote LAN. Where in the firmware do I look for the generation of rsyncd.conf so I could change this, if possible?
Thanks
