NFS ports are by default random so probably they are blocked by firewall.
If you wish to use firewall with NFS please open a support ticket on user portal and our support team will be able to provide you small update to enable fixed NFS ports to open them in firewall
I have been investigating further and have discoved that although the NFS option is enabled when I check the status it has failed ? Looking at the manuals the only issue I can relate to this is regarding DNS. I am simply running DHCP from my router for ip addresses and have entered the same address for the DNS settings. Is this not acceptable ? Do I need to setup a proper DNS server for me to use this option ?
I have already tried this but still the same problem ? My biggest worry is thet I can not get the NFS service to start ? Am I right in thinking that I can simply use a DHCP router and use the same address 192.168.0.1 for DHCP and DNS ?
There could be something wrong with the DSS and you might want to try running the Repair Filesystem from the Extended tools then reboot. If you can ping and resolve the name from the DSS in the Console Tools then your DNS is working properly.
I have ran the repair from the extended tools and rebooted. I have then used the console ping command and can ping the ip address of the dss box and pinged successfully by entering its name "dss" ? I have also unchecked and rechecked the NFS option still the service is not running ??
