I have a RB4011 running long-term 6.45.8 and bridging (L2) two LANs. No IP forwarding, no firewalling at all.
Ether1-gateway is a public ip.
Ether1 (another physical interface with name Ether1) with attached VLAN (id 1510).
L2TP BCP tunnel with activated FastPath to another Mikrotik (CHR).
Ether1-gateway FastPath is active for both tx and rx
Ether1 FastPath is active for both tx and rx
Vlan 1510 FastPath is active for rx only
L2TP FastPath is not active.
If I replace L2TP with EoIP, then FastPath becomes active for both rx and tx on Vlan 1510 and EoIP interfaces.
I messed some more time with this trouble and I figured out that if traffic originated from Mikrotik itself (attach IP to l2tp interface and ping anything from it) then I get FP for RX on L2TP. If traffic passes thru the bridge then no FP for L2TP. I want to remind that L2TP is a part of a bridge (BCP).
My L2TP server is a plain simple config with only mRRu set for 1614 and added profile for BCP. Client config is the same. FP enabled on both sides. I don’t use any encryption at all.
Does L2TP support FP for both TX and RX?
Why there is no FP when L2TP is a part of a bridge?
Thanks, but I don’t need any step by step guides
You can replicate this issue yourself. Just add L2TP interface to a bridge (add bridge interface to ppp profile on both sides of the tunnel) and FP disappears.
I’ve told already, that I DO NOT USE any encryption. IPSec is an encryption. I’ve also told above, if you don’t use L2TP as BCP bridge interface, then FastPath for RX side actually works.
Please read carefully before reply.
Could anyone tell me do they have FastPath on regular L2TP interface for both TX and RX?
