sshd 7.8p1 close connection from VMware Fusion NAT Port Forwarding
After upgrading my VMware Fusion (10.1.3) Arch Guest to the latest with OpenSSH upgraded from 7.7p1 to 7.8p1, found that ssh from macOS Sierra (10.12.6) host to Arch guest via local NAT port forwarding failed, but via Arch LAN IP worked, downgraded OpenSSH from 7.8p1 to 7.7p1 fixed the problem. Any idea about this bug? VMware Fusion NAT Port Forwarding setup: VMware Fusion ?

Try "IPQoS lowdelay,throughput".

Try "IPQoS lowdelay,throughput".Sorry, should be separated by whitespace: "IPQoS lowdelay throughput". (This restores the pre-7.8 setting).

Try "IPQoS lowdelay,throughput".Do you have any insight into what is breaking here? I don't believe changing the default DSCP values should break connections... -d
