I'm running an SFTP server on one of my computers, connected via ethernet to my RT-AC68U running the latest Merlin firmware.
When I access the server directly using its internal IP address from another computer connected to Wifi I'm getting on average 44MB/s download speed. I have made the server accessible to the outside with the relevant port forwarding. If I access it using the router's external address ****.asuscomm.com from inside the network I'm getting 24MB/s download speed, just over half of what I'm getting using the direct IP.
I was initially concerned that when accessing via the asuscomm address the traffic would somehow transit outside the network, but after checking the traffic monitor it is not the case, the WAN connection stays roughly at zero during the transfer.
Is there some way to improve the transfer speeds when accessing the server via the asuscomm address, or is it just the case that the NAT loopback does restrict the transfer speeds? Thanks for your advice.
