Synology DSM driver for Realtek RTL8152/RTL8153/RTL8156 based adapters
This is an RTL8152/RTL8153/RTL8156(2.5Gbps or 1.0Gbps) driver package for Synology NASes.

You can download drivers from the release page and determine a proper driver for your model from knowledge base of Synology,
I very much appreciate it if you could report whether it works. If you have any problems, the Troubleshooting page may help.
NOTE: I recommend using front ports to connect devices because some users reported stability issues when they use rear ports.
The author uses the following environments daily and has confirmed that they work stably.
BCM53161
: x3 2.5Gbe / x2 10Gbe)RTL8372
: x5 2.5Gbe / x1 10G SFP+)
INFO: Products using RTL8156BG have dramatically lower power consumption(up to 64% decrease) and heat generation than those using RTL8156.
See the Compatibility page for the latest information.
Enable SSH and login your NAS.

Warning: Do not use Safari for this operation.
You can configure the IP addresses and MTU of the added NICs from the DSM UI in the same way as the built-in NICs.
Option: I recommend setting MTU to 9000 and SMB protocol version to v3 for better performance.
