Openwrt Shadowsocks Server traffic passthrough

Hello, We have a Shadowsocks Server installed and its working with local windows client. We also has openwrt router that has Shadowsocks client installed. We want to pass through Shadowsocks Server traffic through below IP range
192.168.5.5 - 192.168.5.10 . If you have experience in openwrt pls let me know. I think without experience in openwrt its hard to do the job.
