Well I’ve not been able to make it work within the same machine 😥
I’ve been able to reroute to another PC in the local area network but it doesn’t totally work either. This is roughly what Ethereal reports:
PCA -> SYN -> PCB
PCA <- SYN/ACK <- PCB
PCA <- SYN/ACK <- PCB
PCA -> RST -> PCB (ZeroWindow)
