You are.

The laptop needs forwarding enabled:
10:13 [summer at numbat ~]$ grep ip_ /etc/sysctl.conf
net.ipv4.ip_forward = 0
08:19 [summer at numbat ~]$
Change that to 1. "man sysctl"

Hosts on each side need route set so the can find the other. "man route"

Use of tcpdump on the laptop can help sort out where packets are being 
lost. "man tcpdump"
Something like this:
tcpdump -i any host a and host b
Hosts  a and be are on opposite sides of the laptop.
