hi, guys.
i need to have this solved to put my m0n0 to work.
it's actually the third time i post it, but nobody ever responded

well...
with the help of couple of you, at least now i'm conscious about what 
my problem is.

the gateway that my ISP's DHCS provides me, sits outside of the IP 
network (and changes sometimes).
now...

from the DHCP i get this

IP: 213.84.18.xxx
netmask: 255.255.255.0
gateway: 195.190.249.11

the DNS's are

194.109.104.104
194.109.6.66

looks like freeBSD (differently from Fedora or other "easy" distros) 
doesn't accept this kind of "difference".
i think this should be solved in the m0n0 distro instead of trying to 
add routes and stuff like that.
every time i add a net to the routing table, it gets deleted after a 
while because the WAN interface
is set to work as a DHCP client.

and they talk about manually adding -net and routes

how to make these changes be permanent (considering i'm not that 
network or Linux expert?).
as far as i know Fedora is one of the linux distros who's not affected 
by this (not sure, though).
infact my fedora was working perfectly when connected to the ADSL modem 
as DHCP client.

is there any GURU around that can help?

as always...
thanx guys for all your help

ciao.ubi
