I am using HAProxy to load-balance RDP connections between clients and RD Gateway server.
There are two RD Gateway servers(192.168.0.10/192.168.0.5) behind HAProxy, the balance method is
ROUND_ROBIN, and stick session by
Here is my config:
global daemon user nobody group haproxy log /dev/log local0 debug alert log /dev/log local1 notice alert maxconn 2500 stats socket /var/lib/neutron/lbaas/v2/7ee12684-c45d-4af4-8ae7-381743beb78e/haproxy_stats.sock mode 0666 level user defaults log global retries 3 option redispatch timeout connect 5000 timeout client 50000 timeout server 50000 frontend 377c24a1-1735-4947-a854-0d1fb8d0cd97 option tcplog maxconn 2500 bind 192.168.0.7:443 mode tcp default_backend 51d6cead-368e-45a3-bcda-b1fb8cd5f2dd backend 51d6cead-368e-45a3-bcda-b1fb8cd5f2dd mode tcp balance roundrobin stick-table type ip size 10k stick on src timeout check 5s server 3ccbdfa9-fa69-4388-ad1b-046731825659 192.168.0.10:443 weight 1 check inter 5s fall 3 server 7dde5bd2-ad90-4668-9642-466446646948 192.168.0.5:443 weight 1 check inter 5s fall 3
It works but I found that when the backends RDP session is disconnected from RD Gateway(I can see the disconnected logs from Event Viewer), clients connection doesn't stop, I still can see the VM's screen(but can't do anything), it means that the session still keeps connected, why?
What I expect is the frontend should get disconnected info from the backend and try to re-establish the connection again(cause the session has already disconnected from the RD Gateway server).
Is there any miss-configuration? I have no idea about this issue, any help is appreciated.
