Accessing bridged modem on same subnet as LAN

RouterOS Beginner Basics
1

Hi

I have an RB2011 desktop device. My DSL modem is bridged and connected to ether1-gateway which my PPPoE connection dials through.

The modem is using 192.168.88.10 and my LAN subnet is also 192.168.88.x

If I try to browse to http://192.168.88.10/ via the LAN it just times out.

How can I enable access to this page?

Assuming that you want the RouterBoard to act as a firewall the easiest way to resolve this is to either:

a) Change the modem IP
b) Change the LAN subnet range

If you change the modem IP to say 192.168.77.10 then also add the address 192.168.77.1/24 to your RouterBoard Eth1 interface.

If you should then me able to see the modem at 192.168.77.10 from the LAN - assuming that the firwall settings allow that traffic.

You could also handle this another way using proxy-arp but I think it would be tidier to change the IPs.

Perfect thank you. I changed the router IP to .77 and added the subnet to the eth1-gateway and works like a dream :slight_smile:
