Hello all,
Is it possible to limit the number of concurrent connection (input/output -
tcp/udp) each IP (node) can have at any given time?
Thank you,
Carlos

Not to be a stickler, but does connlimit have a way to control the total
number of combined in AND out bound connections a host has? I.e. if you
were to run this on a gateway where you wanted to limit a computer
behind it to a grand total of 10 connections? Wouldn't connlimit
usually be applied in such a way as to watch traffic in one direction
and another rule to watch the traffic in the other direction? I.e. 10
outbound connections in addition to 3 inbound connections thus totaling
13 connections? Or does connlimit take care of this internally?
I think an answer that I have seen to this in the past has used bridging
where you would watch for packets entering the bridge and leaving the
bridge at the same time. This way, one rule would catch all inbound AND
outbound traffic.
Thoughts / comments / opinions / suggestions are welcomed.

That does not exist yet AFAICS. You would have to combine hashlimit with
connlimit, creating a new kernel module, somehow...
