The first machine (let's called it A) is connected to a LAN. The second one (B) is attached to A via PPP. A is also doing proxy arp for B. How do I make A forward broadcast packets between B and the LAN? I tried to turn on the sysctl variable net.inet.ip.directed_broadcast but the variable does not seem to exist. kt
