Our WAN1 port is connected to an ADSL modem and uses PPPOE to connect

The connection grants a fixed IP address and is used for company mail and  http access. 

The ADSL modem web management interface is available at 192.168.10.1 on the WAN1 

I thought I could set up a static route to the management interface off wan1 as I did with our last router

I set the static route as follows

address is 192.168.10.1

mask 255.255.255.255    just the one IP

interface : WAN1

Next Hop :  ????   

I was not sure what to set Next Hop to ... I tried our public IP, the WAN gateway IP .. nothing seems to work

How can I access the management interface from the LAN (office) without having to go into the machine

room and connect a laptop to the modem ?
