direct links of old sources may well be a few messages off.

there was a misunderstanding!

I meant your eth1 mask not the eth0 ones.

inet adr:  Bcast: Masque:
                                     ^^^                    ^^^
either this must be 127 -------------+                      |
or this must be 255 ----------------------------------------+

on your 15bit netmask, your broadcast adress must have set all 15 lower bits!
