AW: FIAIF blocks local postfix

[Sebastian Feldmann]

Hi,

i read the page and can confirm that the network configurations
IP, MASK, NET, and BCAST are identical to the ifconfig settings.

FIAIF => ifconfig
DEV   == eth0
IP    == inet address
MASK  == mask
NET   == inet address/mask
BCAST == bcast

Everything else works just fine, i opend specific ports and closed them and got the expected results.

But i still cant deliver mails to our own mailserver.

regards
Sebastian

Please read the 'maintaining' section on the webpage.
(http://www.fiaif.net/maintain.php)

In short, A packet is reported (and dropped) as a martian if it has an 
illegal source or destination address compared to the interface it was 
seen on. I would suspect that the network configuration of fiaif is 
incorrect.

Try reading the man page
