Hi Manuel,

I have executed the 2 commands by visiting /exec.php page and executed both
commands

ifconfig em0 -rxcsum -txcsum
ifconfig em1 -rxcsum -txcsum

When I try to FTP to a server, the Monowall console shows:
in_cksum_skip: out of data by 20

connecting to FTP still not working on VMWARE .
*Note that my LAN and WAN use lnc0 & lnc1
(while my DMZ is setup on em0 & em1 ... executing : ifconfig lnc0 -rxcsum
-txcsum = Invalid argument)

LAN -> lnc0
WAN -> lnc1
OPT1 -> em0
OPT2 -> em1
