SCP stalled

[gmoulard]

Hi,

I have a basic pfsense configuration but the FW is host on openstack cloud with opencontrial.
I dont use NAT on pfsense.

when a use scp I have verry stalled message and my throughput is verry bad.
I have one workaround by scp -C. In this case the throughput is normal.

I think there is link with th paquet size:
…
debug2: channel 0: rcvd ext data 31
100M.bin                                                                                                                                                      0%    0    0.0KB/s  --:-- ETASink: C0664 104857600 100M.bin
debug2: channel 0: written 31 to efd 6
100M.bin                                                                                                                                                      2% 2112KB 596.5KB/s - stalled -debug2: channel 0: rcvd adjust 98329
100M.bin                                                                                                                                                      2% 2208KB 112.5KB/s - stalled -debug2: channel 0: rcvd adjust 114688
..

when I bypass the FW I don't have the pbs.
when I check the "Disable all packet filtering." there is no effect.

Could you have some idea?

see my log in attachement
Test1 with -C
Test 2 without compressions
