Hi all, thanks for the replies.

The network settings are all fine and I can port forward OK to other 
devices on the network.  I can also port redirect OK as well eg. 
telnetting to port 81 correctly connects to another device listening on 
port 80

I already have a reverse proxy running to one of the devices so this 
might be an option.  The only problem is that if the LAMP server goes 
down so does the connection to the data logger.

I try again in the morning and report back.

Thanks again,

Norrie
