Having bandwidth issues between 2 sites.     Site 1 - MX100 on a 100x100mb fiber connection Site 2 - vMX100 in AWS which tested 300x150mb to the internet from a Windows 2016 EC2 instance   Auto-VPN is configured between both sites.  Noticed that a 60mb file copy from an AWS instance to a desktop in site 1 was taking an unusually long time.   Ran iperf3 -c Site2Instance -P 20 from a Windows 10 desktop in Site 1.  Getting 80Mbits\sec to 100Mbits\sec as expected.   Ran it in reverse: iperf3 -c Site2Instance -P 20 -R .  Getting 300Kbits\sec to 500Kbits\sec.   Bandwidth issue appears to be one way only.   I also tested iPerf outside of the IPSEC tunnel using the AWS instance's public IP and I was getting 80Mbit to 100Mbit\sec as expected.   I've played with MTUs between endpoints and also had Meraki support set MTU on the WAN interface of both MX's.   Something in the auto-vpn tunnel is throttling bandwidth and Meraki support can't figure it out.  Anyone run into a similar issue? ...
