{HELP} Big Problemm

Hello everybody, i have a problem, when i go ip - apr, i see all ip addresses with the same Mac Address,and i must disable mac address, and ip address to get out of this problem, and until i format this pc i cannot enable ip because again he make clone macc addresses, can anybody tell me what is this problem…
With respect..

don’t you use proxy-arp on neighbour MT? =)

No i dont use Proxy-arp, i only have configured the router, and it wokrs so well, but the client is infected , and you know he make like this..

IP address Mac Address Interface
192.168.2.90 00:01:6C:89:1B XXXXXXX
192.168.2.91 00:01:6C:89:1B XXXXXXX

but in reality the must have different Mac addresses, just when i discconect it, or when i format his Pc, that is the only way to work Internet of theyre clients…

is this arp-poisoning attack? use static arp entries

man, i think you dont know the problem yet, everything its Ok but when a computer is infected immidiatly his Mac Address clones in all other ip address, and you must just to restart Antena, and you will have internet just for 1 minute, and when i format his pc, it wok’s well..can you tell me youre email adress and we will takl

WIth Respect alternativi..

P.S, if you wanna my email address ylberi_boy@januzaj.com

his MAC clones to all ips in segment? or only empty, or even all ips even not in segment?
if first case - it is symptom of arp-poisoning

mac address clones to 50-95% of costumer, and these costumer dont have internet connections until i disable this mac address..

so why don’t you use static arp? or if you use DHCP, set ARP to reply-only and check ‘Add ARP for Leases’ checkbox

man, i dont know , i need help, so what do you suggest me? i think that suggestion tell me how can i do that thing

If a customer is causing the issue, we would remove him from the network until they got the computer looked at.
For us it means going in and disabling the port or turning off his account.

do you use static IPs or DHCP?

i use static Ip address, and all ip address are x.x.x.x/30

THANK YOUU..

so make ARP entries static (in WinBox right click - “Make static”)

so what is the differend of Dynamic ARP, and STATIC ARP??, and please can you give me youre email address..we will talk better..thank you

with respect

with your permission, I’d like to talk here, so other people can read when necessary =)

dynamic ARP is updated realtime. static entries are not changed, only manually

so when your problem client tries to poison ARP tables on devices, dynamic entries are changed, but static entries remain correct
