max. amount of connections?

Mon Nov 29, 2004 1:26 pm

Hi everyone!

I'm getting the impression that the Mikrotik RouterOS does not allow more than 1000 (1024?) connections. Am I right here?
Regards,
Evert

No. We normally have 5000-7000 connections. 15000 on occasion.

Weird... Could it perhaps have to do with the line capacity then?
It can't be the hardware, because I'm getting more or less the same results both on a 2.4 Pentium and on a 133 Mhz Via...

Also if you would like to see the number of connections you can go to the terminal and go to the IP Firewall Connections menu and type print count-only and it will show you the number of connections.

It was running at about 5mbps (The MT box restricts local to 5mbps), as the traffic was running around our 10mbps wireless network and going out to the internet.

This is running on a P200 :) Lookin at the CPU Usage, it was gradually going up as the traffic increased and eventually couldn't handle the load. I suspect the p2p mangle rules I have bombed it, as they are very CPU intensive.

I will be upgrading the box soon to stop this happening again.
