hello thanks again!
ok, i agree my solution sounds not very simple =) i never made something wit carp. i will see the manpage and will try to find and read some docs. what i'm really dont understand is: how can carp to loadbalancing. if i get an arp answer from the first router, the next request for this ip will go to the same adress. so carp has do do "mac faking"? is carp "flooding" the subnet with random mac adresses for the same ip? thanks, regards marco Am Sonntag, den 29.01.2006, 13:59 +0000 schrieb tony sarendal: > On 29/01/06, Marco Fretz <[EMAIL PROTECTED]> wrote: > > > ok thanks > > > > i think, 400 Mbit/s throughput should be enough for this usage. > > > > another question: does anyone know if there is a network card that can > > do something like cisco wirespeed routing? or is there anything that can > > handle software and hardware routing on a normal intel box? > > > Cisco wirespeed routing ?
