Hi everybody,

ok, I recognized another linux network problem that I solved now. Situation now is like following:

When I call my upstream address via curl (on the nginx host) by selecting the corresponding local interface (eth0-9 = 192.168.1.130-139) everything is fine.
curl https://192.168.1.21:443/remote/events --insecure --interface eth0

But when I specify the same IP address that refers to eth0 (eth1-9 etc.) I get an "110: Connection timed out".
Does anybody know this situation? Checked by sysctl config but it looks fine...

split_clients "${remote_addr}${remote_port}AAAA" $proxy_ip {
100% 192.168.1.130;
}

server {
listen 44301 ssl backlog=163840;
proxy_bind $proxy_ip;
#proxy_bind 192.168.1.130;
..
