[Fwd: Re: TCP/IP between L4Linux and L4 task]

Hi,

I have a question for some time - why not use flips as a simple gateway?
Maybe it is better than configing the nic to promiscuous mode?

I have made a simple test, and it can work. I think another merit is that we
may use the ipsec implentation of linux kernel with flips.

Regards,

Wei
