Just purchased a new AX21 for the expressed purpose of using the OpenVPN client to connect the router to NordVPN. I was able to successfully install/configure the client to NordVPN server. However, I then found that my upload/download speeds were severely limited. Without the VPN active, I could get ~200 Mbps download and ~110 Mbps upload speeds. Once those devices were added to the VPN Device List through router GUI, the download/upload speeds declined to ~11Mbps/~1 Mbps, which is unacceptable.

NordVPN Support validated proper configuration and concluded the processing power of the router was the bottleneck. I did not validate this through the performance (cpu/memory) stats of the router at the time. Does anyone have a similar VPN client configuration the AX21 and have been successful without the severe throughput degradation? Nord indicates the encryption/decryption process taxes the router resulting in poor upload/download speeds....

Does TP-Link publish any benchmark results for the AX21 when utilizing VPN client?

thank you in advance
