Hi, I have added 2 machines (A & B) in ZT. I’ve installed Haproxy and A to relay all the traffic towards B using managed routes. I have installed a proxy on B i.e. with the help of Haproxy, when I connect to server A, I will be redirected to server B.
The case is if I run speedtest(multi-thread mode) on my mobile devices to see how much speed I can get, server B will lose connection. The ping result is presented below. During the speedtest, destination host unreachable pops up and ofc speedtest is stopped.
Server A:

I tried different servers but all stay the same.
Tried
- Trusted path added
- New ZT networks
- added net.ipv4.conf.em1.rp_filter=2
- systemctl stop firewalld
- Increase Multicast Recipient Limit
- Disable Broadcast (ff:ff:ff:ff:ff:ff)
Question:
Any hint on this issue? Is it possible that the network provider bans this? But I tried machines from different data centres and all the same. Some data centres machines are fine, but some are not.
