Re: [Xen-users] Firewall in domU, networking in XEN

hi slawek,

1 comment only so far, until u begin u should know what u want. all wished 
features can be set up by xen, no prpos but dhcp firewall ... with 1 nic ...

that sound really mess'y

not xen is here the nut, the overal concept!

u want all services and all security with minimal hardware (nic).

in switzland we say: u can have the bread and the 5p at the same time :)

thanks walter
