If u disable encryption, u use less CPU, is form of optimization. Doubt it is your MTU. If you set yes for MTU in client profile, mikrotik will dynamical create firewall rules that correct your MTU.
Never said any thing about simple queues. If you have got 1500 PPPoE connections with queue rules, you would probably have to look at a PC based mikrotik solution. Have got a RB 1100 with 150 users and the CPU is hitting 35%.
Have a look at http://www.routerboard.com
the specs on the RB will be there.
If you like to see my picture that I posted here please open this forum with Mozilla or Safary web browser.
I have setup the MTU in all equipments:
Wlan1=1500 PPPoE Client=1480
Wlan1=1500 Ethernet1=1500 Bridge1 (ether1+wlan1)=1500
Ethernet2=1500 PPPoE Services MTU=1480
On the PPPoE Server IP/firewall/Mangle I have created the rule to CHANGE MSS TO 1440
Again My question is:
Do you think that I need to change the MTU to 1480 in all equipment or only that into the PPPoE Services MTU?
I apologize because I dont tell you that we have installed PPPoE Server by Main Towers and our PPPoE Server are:
1-50 clients We use RB493
50 - 180 Clients we use RB1100
180+ Clients we use Dual Core PC
What is your opinion about the MTU - please see my graphics picture using safary or mozilla
