I am running several services behind IPFire that create a mass of TCP Connections.
At the moment I am running into the problem that, apparently, IPFire has a maximum limit of 16384 open connections. I need to increase that limit, as I am running into problems with connectivity because there are no more free connection sockets.
I searched, but did not find an answer so I ask here. Is it possible, maybe via root shell, to increase the limit?
I did some digging for example echo “1024 65535” > /proc/sys/net/ipv4/ip_local_port_range and some sysctl tweaks, but nothing seems to take effect.
