I have two RB2011 units used to create a layer 2 bridge between two sites. We used PPTP server/client with PPP handling the large packets so we can transport full size Ethernet Frames
We tie the the PPTP-Client interface and the VLAN8 (Eth5) Layer 2 to a bridge as documented by MT.
We are seeing substantial packet drops so I am trying to (1) debug the packet drops and (2) apply some traffic shaping of small vs. large packets.
We see RX Errors and RX Drops on both sides of the connection. Any ideas on how we can debug the packet drop would be greatly appreciated.
I setup a mangle rule to mark packets arriving on the VLAN8 interface and shape them out to the pptp-client interface. I also tried applying the rule to bridge without success, I never get any hits on the mangle rule. Am I doing this wrong way?
