[LARTC] Can I limit traffic rate to 5Mbps in both direction (in and out)

["openings" <openings@xxxxxxxxxxxxxxxxx>]

Hi.

I have two NIC in Linux machine. 

One NIC is out direction(to WAN), the other is in direction(to LAN).

I want to limit traffic rate in both direction.
(total 5Mbps limit to destination port 80 traffic in both direction)

but I can limit in only one direction each.

How can I limit traffic in both direction ?

Thanks.
