Hi, how to ping to bridged modem either from LAN or MikroTik?
Here is my topology:

Internet --- ADSL Modem (Bridge) --- MikroTik --- Switch --- LAN

ADSL Modem (Bridge) = 10.0.0.1
MikroTik pppoe (ether1) = 10.0.0.2
MikroTik LAN (ether2) = 192.168.1.2
LAN = 192.168.1.xxx/24

Now I can't ping from LAN to ADSL Modem (Bridge) and also I can't even ping from MikroTik to ADSL Modem (Bridge), but both MikroTik and LAN can ping to google.com
I think it should be some routing to make this works.

Please help, much appreciate. Thanks.

Could the modem possibly be blocking icmp?

Can you ping the modem if you plug directly into it with a modem. Do you have same net mask on modem and router

yes... this is solved, thats my modem problem, i found out by plugging directly from pc to modem and I still can't ping to modem...
then I reset modem and it works perfect...

Thanks very much for your help

I can ping and get to the configuration page on my modem from my LAN even though it's in PPPoE bridged mode.

My LAN is 192.168.1.0/24 and the modem is on 192.168.2.254/24. I have set an extra address of 192.168.2.100/24 on the ether1-gateway port of my 751 which the modem is plugged into. The important thing is that the modem can be set to have a default gateway of 192.168.2.100 and also DNS is set to 192.168.2.100. Some modems don't allow a manual gateway address on a LAN. Netcomm doesn't appear to but Billion does as it lets you chose IPWAN or IPLAN for the gateway and DNS address. Because the Billion allows IPLAN gateways I can also still use the Billion's VoIP function without any trouble.
