Hello
We is testing the limitation of the bandwidth by IP address with mikrotik 2.9.13, we have a problem with simultaneous connections when we download from the same Web server, we launches two downloading at the same time it is good and that functions, but when we launches a third it is put on standby, an idea on this case ?
regards
NB : we have upgrade th OS from 2.8 to 2.9.13

for single IP add.
ip firewall filter>
chain=forward src-address=192.168.1.10 protocol=tcp
connection-limit=30,32 action=reject
reject-with=icmp-network-unreachable

and this for all IP's
ip firewall filter>
chain=forward protocol=tcp connection-limit=30,32 action=reject
reject-with=icmp-network-unreachable

is this ok?

Isn't there an IP address conflict??

Or maybe the webserver you are downloading from has a connection limit per IP? Thats quite common. If you use NAT and masq it will drop more than 2 connections form same IP.

This is a limitation of microsoft ie. I think it can be adjusted in the registry somewhere.
