Routing Problem

RouterOS General
1

I have a RB750 setup as the main router with ip 192.168.88.1 acting as dhcp, dns and nat to 192.168.88.0/24 users

i setup pppoe for customers so i bought a second RB750 and configured it as follows:
wan interface: port 2 as master port with ip 192.168.88.234/24
pppoe interface: port 3 master port with ip 10.10.10.1/24
port 4 and 5 are slaves to port 2

i have multiple access points connected to port 3 (the pppoe port) which are assigned 192.168.88.x addresses
my question is how can i ping these access points from the 192.168.88.0/24 subnet.

another problem is i have the same setup with a third RB750 (hotspot) that is configured as follows:
hotspot interface: port 2 as master port with ip 172.16.0.1/24
wan interface: port 3 master port with ip 192.168.88.235/24
port 4 and 5 are slaves to port 2

access points are connected to port 2 (the hotspot port) which are also assigned 192.168.88.x addresses
how can i ping these access points from the 192.168.88.0/24 subnet.

Thanks

You would probably be best to move away from the Mikrotik default 88 subnet and design the IP layout properly, but meantime you can try running proxy-arp on the “WAN” interface / port 2 of the second 750. The second 750 will also need to have a default path via the first 750.

and by default path you mean that I have to add a default route in the main router in IP>Routes ??
what should the default route be like

Thanks CelticComms :slight_smile:

If the second 750 has its 192.168.88.0/24 port connected to the 192.168.88.0/24 interface on the first 750 (directly or via a layer 2 device such as a switch) then simply running proxy-arp on the 192.168.88.0/24 interface on the second 750 should suffice. Essentially that will cause the second 750 to respond to ARP requests on 192.168.88.0/24 for IPs that it is allocating to PPPoE clients.

i changed ether2 on the second RB750 to proxy-arp but still i cannot ping 192.168.88.xxx IPs that are assigned on the PPPoE interface (eth3) :frowning:

CelticComms,
if i try to ping from the second RB750 in tools>ping to a device in eth3 (pppoe) interface let’s say 192.168.88.210 i get a arp entry automatically in IP>ARP but the ping is timed out.

Are you seeing entries in the routing table for these 192.168.88.x PPPoE clients? Are you sure that the PPPoE clients are configured to accept pings?

CelticComms I’m not tryin to bing the PPPoE clients, i’m tryin to being Access points on the eth3 (PPPoE) interface that have 192.168.88.xxx IPs
i’m connected to the first RB750 I have the same range as the access points but I cannot ping them.. that’s the problem
