[USG LITE 60AX] NAT rules limit is 10?

Hi there,

I am using USG LITE 60AX as my security router for home. There’s a Synology NAS behind USG LITE 60AX. I am trying to set NAT rules to have most of services provided by NAS able to be accessed from internet. However, the limit of NAT rules becomes the showstopper and I have no idea how can I do.

Can you provide your suggestions?

Thanks
