I'm using several ASUS RT-16N routers (Easy Tomato .08). They are connected using OpenVPN tunnels. Everything works great over the VPN except for the file transfer speeds using the NAS/Samba file sharing, the most I can get is around 250k. Not using the VPN I can get 8M+ file transfer. I did not expect to get all of that over the VPN, but I had hoped for more. Other programs using the VPN connection can get up to a 1m transfer rate. The internet connections on both ends should not be a limiting factor 30up x 30down & 2up x 15down. Are there any setting I can modify to help this issue?
I also setup the FTP with similar results.
