Awfully slow transfer speeds from remote NAS over ZeroTier
-
@stephenw10 Correct, 16MB/s aka 128mbps which is far less than what I am getting, but much faster than before. UDP traffic from the NAS was being blocked over WAN.
I cannot access the NAS without VPN, so there is no way to test that theory. Network works great, I haven't had any speed issues until I got this set up.
-
But you see the expected WAN speeds up and down at both ends? Through pfSense?

@stephenw10 I was able to resolve this after more troubleshooting. thanks!

For someone in the future who might have a similar issue and finds this thread via a search, would you mind sharing what you found that resolved the slow remote transfer speeds for you?

But you can do this : https://forum.netgate.com/topic/195855/weird-slow-openvpn-connection/4 and suddenly you have a full 1 Giga bits /sec or 125 Mbytes / sec connection between your test device (using OpenVPN, or, why not testing without it also while you're at it), pfSense in the middle, and a NAS on the pfSense LAN.
I'm pretty sure that that pfSense (the OpenVPN process actually) can handle just fine many M bytes / sec. It's more a "what processor do you use ?" question.
And its always a "how did you set it up question"

@bmeeks I was able to resolve after turning on UPnP & NAT-PMP on pfSense. I didn't realize ZT would need to have that on to dynamically map external ports and avoid NAT traversal.

Thanks for the follow-up. Just thought it would be helpful to another user in the future that might experience the same issue to find a solution in your thread.
I know I have personally found threads on other forums when searching where the problem matched something I was experiencing at the time, but the original poster closed out their discussion thread with the equivalent of "I solved it", but without saying how
. -
@bmeeks No problem! I should have posted the solution initially. Makes sense, it will be helpful for others!

Yup good to know that about zerotier, I wouldn't have thought it was required.

According to the documentation, it is not required for holepunching, but they do refer to challenges with symmetric NAT.
