yeah I changed the name to its 192.168 IP address and that works across the network ( is that what you meant?) but when it come to trying it across the internet with its router Ip address forwarded im not getting much luck. Any suggestions would be greatly appreciated. Thanks
First, check that the port forwarding is working as expected by running a packet sniffer (e.g. ethereal) on the local machine to see if it ever receives the packets on port 1099.
Second, run the packet sniffer when connecting over the local LAN to see if RMI is sending packets to any other ports that you may also need to forward from the router.
Third, check that you haven't got any additional firewalls anywhere, or on the router, that are blocking the port even though it's being forwarded.
