I’m not sure what I’m missing but I can’t seem to get fastpath working on RB750GL. ROS 6.30.4
I have simply bridged the interfaces.
Fastpath is checked under IP services
No firewall rules.
Connection tracking is off.
No queues
All the other conditions under http://wiki.mikrotik.com/wiki/Manual:Fast_Path seem to be met yet the IP4 fastpath remains unchecked with no packets showing.?
What interfaes do you use? what other config do you have?
Config below, have replaced sensitive bits with XXX
Pretty much all it's doing is routing.
DHCP is on.
OSPF is disabled.
Firewall rules, NAT disabled.
Bridge filters disabled
No queues yet..

As far as i can see, bridge filer stops you from using bridge fastpath, try diabling it, to see if that helps.
They’re disabled anyway. I only used them temporarily whilst converting network from bridged to routed.
