UPnP port mapping table size

My Synology DS216+II NAS comes back with an error when it tries to rewrite the table.
It seems it is exceeding the max, or thinks so
I'm not mapping many ports, and my old Netgear CG3000v2 cable modem handled it.
Any thoughts?
Thanks in advance
David

My R8500 is limited to 40 and my R9000 is limited to 100.
I too have a Synology NAS (DS1812+). That's how I know how many entries each router can handle.
Another option is to use this tool:
https://github.com/kaklakariada/portmapper/releases/download/v2.1.1/portmapper-2.1.1.jar
Keep adding entries... fake ones are fine... until you hit the limit.

Re: UPnP port mapping table size
I've trimmed the number of ports it wants to use to mid 20s and it's working without complaint.
It was only trying to do 48 max before that, so I assume its probably 32 it can actually handle.
Disappointing when my ancient cable modem / router was 100
It's a simple stat about the product yet not to be found anywhere.
Tech Support just referred me to call Singapore
Well, it's chugging away now so onto the next issue
Thanks
