I use OpenBSD firewalls with NAT and redirect and it works just as it's 
supposed to. 

That's not even half duplex. In half duplex each side Can talk, but only one 
at a time. It seems to be an error with configuring your firewall. (One 
common error is to only turn on redirect. But you also need to Allow the 
traffic to flow...
