Very strange situation , for example: I have users using PPPoE connection to my MTrouter and user using internet the old fashion way, they have public IPs and internet access but they can’t transfer any data between them.
Any ideas ?
check the route 
is this the same MT ? if not does MT1 (normaln user gateway) know about MT2 and what ip adress are there ?
Sounds like subnet mask problems. Every computer within same subnet has to be able to reach each other on layer 2
Please elaborate on your configuration if you need more help.
I am successful by using following way to passing PPPoE connection and public IP with same MK.
Hope this will help you.

Hi All, thanks for the replays
I must clear some things of my MT router setup,
1.All users (the PPPoE and the normal one) have internet, they can download files and browse www pages
2.All PPPoE users have connection between them – PPPoE user1 can ping and transfer files with PPPoE user2
3.All normal users have connection between them – normal user1 have ping and transfer files with normal user2
4.All users use real public IP addresses andt thea all are from one network – 82.82.82.0/24 for example
5. normal users have 82.82.82.254 for GW and PPPoE users have default profile with Loacal Address 82.82.82.254 and secret Remote Address 82.82.82.1 , 2 , 3 …..
Bottom line all PPPoE and normal users are setup to be from one network.
The problem is that PPPoE user1 have connection with all other PPPoE users and anywhere in the internet but don’t have connection to normal user1.
Ok, i still stand by my answer
Hi Sten
the normal user use 255.255.255.0 netmask the PPPoE by default are with 255.255.255.255
i don’t think that MT support netmask change for PPPoE
so they get a unique /24 each?
Sten, I think you misunderstood him.
His “normal” (non-PPPoE) users do get addresses from a /24.
His PPPoE users do get addresses from the same /24, but with a /32 netmask (which is ok for the PPPoE link).
I think the problem is that the non-PPPoE users do not see the need to go through a router to contact the PPPoE users’ ip address, as they are in the same subnet from the view of the “normal” users network config (/24 subnet mask).
But they would need to go through the router/PPPoE server to reach the PPPoE users.
You could try to subnet your /24 for your tow types of users (i.e. the first half for static ip customers, the second half for PPPoE users).
Other solutions seem possible, too…

I didn’t, i was just trying to get him to think.
I’ve already informed about the details.
Every host within same subnet has to be able to reach each other on layer 2. Every host outside that subnet need only reach each other on layer 3.
The normal users consider the pppoe users to be in their subnet.
The pppoe users do not consider the normal users to be on their subnet.
You can either split the subnet and lose a few addresses, add several host routes on each normal host or enable something on the pppoe server that will trick the normal users to think that all traffic to the pppoe users shall be sent to the pppoe servers mac address (Proxy-arp).
