Hi,

I’m investigating a setup with the returning data from a DNAT rule is going 
extremely slow.

Example rule looks like this:
DNAT            net             $DMZ_MAIL:22    tcp     9022    -       
pu.bl.ic.ip

interfaces
net     eth0            detect          tcpflags,nosmurfs
loc     eth1            detect          routeback

masq
eth0                    192.168.60.0/24 pu.bl.ic.ip

params:
DMZ_MAIL=loc:192.168.60.2


Using SCP copying files to the server gives as full speed as my internet 
permits. Receiving files throttles the traffic at around 2-3KB/s.



regards,
Robin
