I have the same problem! I use different Dell 1u servers but the problem is on all of them. I wonder if this is a Broadcom issue? Anyway, I to blame the ISP but the problem is still there with the new ISP. I have gone from 2/2 SHDSL to 10/10 fiber. Same problem. Cant get any good outgoing traffic. I have many different locations; I have one 100 Mb fiber connection witch gives me 1 mbit upload, One 10 Mb fiber connection witch gives me 200 k upload and one 1/1 SHDSL witch gives me 20 k upload. I have tried with the latest beta release with no luck. If I cant find a solution to this I have to trash all my Monowall and that is a shame since I have used this the last 5 years.... Anyone who has a solution??? Please....
Btw: When you open a PPTP connection (from outside) to one of the Monowalls I get full outgoing and incomming speed. Not from the inside (Lan) and not thru IPsec. This is not only restricted to FTP it is on all outgoing traffic
