PPPoE can't assing IP, it alway uses IP that are used

Hello
Like I’m contineous writting, I’m implementing an PPPoE server with Public IP address, and now I have a little problem. :frowning:
When a client try to connect the PPPoE Server accept the connection, and give an IP of the pool-address, that it’s used, and then kill that client. Look I will paste the log:

21:16:28 pppoe,ppp,info : connected
21:16:28 pppoe,ppp,info,account juancito logged in, X.Y.Z.246
21:16:28 pppoe,ppp,error could not add address: already have such address (6)
21:16:28 pppoe,ppp,info,account juancito logged out, 0 72 101 6 7

And if I look in ppp active connection I see that its IP is used:

ppp active print
Flags: R - radius

NAME SERVICE CALLER-ID ADDRESS UPTIME ENCODING


112 R puca pppoe 00:02:6F:0A:43:A7 X.Y.Z.246 15m5s

That Client can connect, but like 30 minute, or a hour with a lot of attempts
This happens when the server have like 120 clients connected, if only are a few its don’t have problems. But I have like 150 simultaneous connections!! :confused:
Someone, know how can I resolve its
Thank

Can u plz tell us, which version r u using???

And details info. about public ip subnet which is used in ip pool.



thnxs..

Wait, why there are two clients who use the same IP address ?
Do you have big enough address-pool, that all clients can get address ?

Hello
thanks in the help!!
I’m using RouterOS v 3.13, and also I tried with v 3.11.
And about you ask sergejs:

Wait, why there are two clients who use the same IP address ?

I ask the same, because MKT give this IP automatically from the pool

Do you have big enough address-pool, that all clients can get address ?

And my Public IP address Pool is a C class, from X.Y.Z.2 to X.Y.Z.254, but I don’t think that is the problem. When I use private IP address with nat, I used two class C like a pool, depending in the profile. But now, that I have a Public Class C, I don’t want to see how much I have in a profile and many in the other!! :confused:
Thank again

Did you ever find a fix for this? I am having the same trouble

Hello
There is not solution for this problem, look this topic that talk about it
http://forum.mikrotik.com/t/very-strange-3-x-4-x-5-x-freeze-and-crash-with-pppoe/22670/1
I think that is something with the kernel. I hope that MKT Team solve its problem
