Did you set the receive window high on the client machine? If so, you might try doing it on the NAT machine as will. Create /etc/sysctl.conf with the following in it: # begin /etc/sysctl.conf net.inet.tcp.recvspace=64240 net.inet.tcp.recvspace=32120 # end /etc/sysctl.conf This is probably a rather large receive window and you might try lowering it to 32120 if you have latency or packet loss problems on your cable network. After you have created this file, run: # sh /etc/rc.sysctl These changes will persist after a reboot. See how it goes for you.
