Sadly the one thing I don ' t have much of is time , each unit I ' ve asked to demo has a strict 2 week time limit before it needs to be returned . This barely lets me read the manual as I still have to do all the other IT tasks for 35 users . In the web setup , I made a root password , super user account , added the IP , subnet and gateway as provided by the ISP hosted by our office provider chose port 0 , then set up the LAN IP range , DHCP etc . Most of the other options were the default values . Lets say my internet ip is 2 . 2 . 2 . 28 , the gateway is 2 . 2 . 2 . 25 and the subnet is 255 . 255 . 255 . 248 . I tried to add a Static Route IPV 4 using the internet ip and regular subnet mask and adding the gateway IP as the ' nexthop '. This failed with an error about the ' masking ' being ' too short '. I tried it with the internet and gateway addresses switched , and also using the interface name for the hop instead of an IP address . Same error each time .
