Direct Access to my Modem - No Route to Host

Question

Hi,
On occasion I want to check some of the stats on my Modem
Problem: If I try connect to my Modem Sophos Reports:  The content could not be delivered due to the following condition: No route to host

My Setup =  Sophos UTM 9.305-4 (Home Edition)
LAN (eth0) = 192.168.1.x (Internal Network)
WAN (eth1) = 192.168.0.1  (Modem that I want to Browse)

Question:  Is there a way I can log into my Modem (192.168.0.1) without having to physically plug a PC into it.  I added a second IP to my PC (192.168.0.2) which allows me to Browse to the Modem (but cant acess due to no Sophos Route setup).

Could somebody advise on best method of creating a  “Route to Host” on Sophos please.

Cheers

Hi everyone, found work around: 
 
Enable SSH on UTM, and hit the command line 
Find the interfaces in question "ifconfig" 
Then assign the interfaces the addresses manually. 
 
I have 1 modem @ 192.168.1.1, and the other @ 192.168.2.1. 
So 2 commands on the appropriate facing interfaces: 
"ifconfig INTERFACE 192.168.2.2 netmask 255.255.255.0" 
"ifconfig INTERFACE 192.168.1.2 netmask 255.255.255.0 " 
 
Where "INTERFACE" is your eth interface facing the modem(s) 
That did the Trick! Modems are now accessible internally.
