Traffic Shaping for multiple machines with one nic, is it possible?

Hi,

i'd like to shape all traffic from multiple machines with one pc that runs wondershaper(package is in AUR.).

Example: PCa/b/c-> PCw(one nic+wondershaper)->router->internet

I've set things up on PCw like this:
enable ip forwarding so packages are forwarded from PCa/b/c through PCw to router/internet:

sysctl -w net.ipv4.ip_forward=1

disable icmp redirects so traffic goes through PCw

echo 0 | sudo tee /proc/sys/net/ipv4/conf/*/accept_redirects
echo 0 | sudo tee /proc/sys/net/ipv4/conf/*/send_redirects

wondershaper on PCw

adjust values for downloadspeed/uploadspeed/device (DOWNSPEED/UPSPEED/DEV) in /usr/sbin/wondershaper, then run wondershaper: 
# wondershaper

setup on PCa:

ip address of PCw as gateway:
# route del default
# ip route add default via PCw_IP

The problem is that this only shapes traffic from/to PCw, not the other traffic from PCa/b/c that gets routed through PCw and then to the router/internet.

Is it not possible to shape traffic going through PCw, or how can i enable this?
