iptables and policy based routing together

My problem is I have Virtual Private Servers, VPS in different locations around the world. I have created a mesh by using openvpn. Each VPS phones home and sets up a TCP connection to my RT-AC68U running Tomato Shibby 128. I want to route, without thinking, to the different VPS depending upon the country. Then that VPS is now my exit node. I also run Tor on each VPS.

The VPNs are setup and working. I have added a filter on INPUT that only allows sessions to initiate from home.

# iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT

This prevents someone who accesses the VPS to get in to my home network.

Next I have setup marking packets according to country CN = 86
IN = 91
RU = 7
so on

# iptables -t mangle -m geoip  --dst-cc CN,HK -j MARK --set-mark 86
# iptables -t mangle -m geoip  --dst-cc IN -j MARK --set-mark 91
.....

* BTW how do I debug what fwmark is set?

Now I start adding rules

# ip rule add fwmark 86 table CN
# ip rule add fwmark 91 table IN
......

Now type

# ip rule show
0:    from all lookup local
.....
32763:
32764:    from all fwmark 0x5B lookup IN
32765:    from all fwmark 0x56 lookup CN
32766:    from all lookup main
32767:    from all lookup default

Now I get lost, to me this states only if fwmark == 0x56 use table CN else do not use table CN

I have played with adding routing to the tables

# ip route add <gw> dev <tunxx> table CN
# ????
