Spored mene netmask opciqta trqbva da vurshi rabota...
tova e ot man-a :
netmask n
Set the interface netmask to n, a 32 bit netmask in "decimal
dot" notation (e.g. 255.255.255.0). If this option is given, the value
specified is ORed with the default netmask.
The default netmask is chosen based on the negotiated remote
IP address; it is the appropriate network mask for the class of the remote
IP address, ORed with the netmasks for
any non point-to-point network interfaces in the system
which are on the same network. (Note: on some platforms, pppd will always
use 255.255.255.255 for the netmask, if that
is the only appropriate value for a point-to-point
interface.)
zabelezhi note: ...
Ne sum siguren dali v linux mozhe pointopoint interface da ima druga
netmaska, vupreki che az ne vizhdam problem za tova.....
(zavisi de :) fakticheski, s taq netmaska mozhe prosto da e netmaskata
na route kojto se dobavq ... )
Taka che ako opciqta ne raboti, shte ti preporucham da pravish
ip route add xx.xx.xx.xx/28 dev $IFACE , vmesto toq ifconfig...
