Hi Everyone,
I fixed the issue. Nothing to do with NOX, my machine was just set-up
incorrectly. Just for the benefit of anyone in the future. If you are using
an existing Linux box to run NOX and openflow. Make sure you remove all
IPTABLE rules and assign no IP address to all the appropriate network
cards.
The reason I had IPTABLE rules, was the the computer now acting as switch
used to act as a gateway. To remove the rules use this command:
iptables -t tablename -F
where tablename can be any of these: filter,nat,mangle or raw
To assign no IP address to your network cards use the following
ifconfig ni 0.0.0.0 up
where ni is the network interface like eth0
thanks to everyone for trying to help me with this issue.
Regards
Iain
PS all the commands above are not permenant. i.e. after rebooting you will
have to re-enter them unless you modify configuration file.

It's been a while since I've dealt with this. A first thought would
be... try:
cat /proc/sys/net/ipv4/ip_forward
Is it 1? If so, as root:
echo 0 > /proc/sys/net/ipv4/ip_forward
