Containers on different hosts are not reachable - docker

Question

I have a stack with 2 servcies:
1. dockercloud/haproxy as load balancer
2. mycustom/nginx for ssl termination
I have 2 hosts and each service has 2 containers. One on every host.
Host 1:
* Haproxy-1 (IP: 10.7.0.9)
* Nginx-1 (IP: 10.7.0.7)
Host 2:
* Haproxy 2 (IP: 10.7.0.10)
* Nginx 2 (IP: 10.7.0.8)
The problem is that i can't connect from a container on host 1 to a container on host 2.
When connecting on host 1 and trying to traceroute Haproxy 2 (10.7.0.7) i get this:
traceroute to 10.7.0.7 (10.7.0.7), 30 hops max, 60 byte packets 1
10.7.255.254 (10.7.255.254) 2997.863 ms !H 2997.704 ms !H 2997.684 ms !H
Any suggestions how to fix this?

I used dockercloud to setup the services. So i didn't use any commands on my own.
