Hi - I highly not recommend you connect your OXO directly on the WAN.. What are you trying to achieve?

Hi
Thanks for your help
I have network range 192.168.1.0 on lan port for ip phones.
and I have the network range of sip trunk is 192.168.88.0,
the sip trunk gateway is 192.168.88.1.
I want to configure an ip address belonging to this network range 192.168.88.x on the wan port.
but I don't have a wan port on the oxo.
THANKS
