Hi all..
I’m really beginner to mikrotik and networking anyway (and I have a bad english 
). I’m using mikrotik to manage bandwidth of my friend’s cyber cafe.
I’m already success to make mikrotik act as router to LAN, averything works well now, this is simple thing to you, expert guys, buy I have to work very hard to make it 
The problem I can’t make it success until now is to manage the bandwidth. I’m too stupid to understand about queue and mangle, and how to implement it (although I got some example at wiki and forums).
-2 ISP (1Mbps and 512Kbps)
-mikrotik router use 2 gateway (the rule for select gateway currently works well)
-LAN (192.168.1.0) use mikrotik router ip as gateway (192.168.1.1).
-Currently 45 clients connected to mikrotik router.
-mikrotik router is a demo lisence, means I can only apply 1 (one) simple queue.
I want to manage the clients so..
- it have a default limit 64k download and 32k upload
- for some tcp connection using specified port (ex: ftp port) it will limited to 32k download and 32k upload)
- bandwidth is shared equal to all clients
- some clients will be excluded from rule no. 1 and no. 2
Another question is, what’s is the different between chain=forward and chain=prerouting ? I found many example about packet marking using these, but I still didn’t understand when to use chain=forward and when to use chain=prerouting.
Please help me to make this.
Regards, Suki.
