I´m running five accesspoints (RB500) on five different locations. All are connected to a centralized PPPoE Server (via EoiP). Customers are connecting to the accesspoints and "dial in" into the PPPoE Server.
Everything works very fine. But if the pppoe-server reaches about 45 - 50 sessions and a traffic of about 4 - 5 mbit/s (all users together), many sessions get disconnected for 5 to 15 seconds. All wlan-bridge-connections from accesspoints to the pppoe-server are running stable 24 or 36 mbit links.
I examined the cpu and memory utilization of the PPPoE Server, but both is very low. My PPPoE-Server is a 2,4 Celeron with 512 MB RAM. All PPPoE sessions don´t use MPPE.
Did anyone have similar experiences?
Thanks so far.
