PPPoE not woking properly with new router

I have a strange problem going on after a circuit upgrade and new router.
I can’t use the old router with the new circuit.

All of my access points are running pppoe assigned public ip addresses.
They worked fine before the router change.

Now what I am seeing is intermittent connectivity to and from the pppoe clients.

When I ping the pppoe client ip address sometimes it will work and sometimes it responds with a gateway address that is
not the gateway.

  • example - ping 192.168.0.2 where gateway is 192.168.0.1/24. Ping will respond with Reply from 192.168.0.25: Destination host unreachable. Sometimes same ping reponds with different reply address… none of which is the actual gateway.

Needless to say customers are not connecting most of the time.

I used the same ip addresses and routes on the new router. Added necessary firewall/nat rules to permit the ip addresses.
Still no luck.

Need some help soon.

hmmm…
I was natting some clients out with ip’s from the same subnet as pppoe clients.
No conflicts.
Switched the natting to another subnet and tweaked a few firewall rules.
All is well now.
