I've changed my ubuntu NAS to mikrotik and ran into problems:
ROS version 6.15
I have about 700 pppoe sessions, nat, 400 mbit max bandwidth.
I have double port Intel nic, ROS shows: 82576 Gigabit Network Connection (rev: 1)
Port 1 is for uplinks, 2 for downlinks, 100 vlan ifaces there.
After a several hours working I have packet loss on downlink port.
Trying to ping internal pppoe customer IP's from router and see 105 (no buffer space available).
Uplinks works as usual, cant's see any drops. Reboot helps for some time.
Downgraded to 6.7, now testing.
I suppose x86 is not the choice for new ROS versions, should migrate to CCR?
