arp-poisoning help !!!

Mon Dec 22, 2014 6:56 pm

Hello,


I have a situation and need litle help :), I have a link conection to my ISP with a static public ip address and mask/29!
I have been disconected because I am arp-poisioning ISP-es range of /24 ( if I understood them correctly, is a fresh problem maybe they are wrong ).

Last few days I whanted to test option proxy-arp so I can use rest of my public IPs and give them to my customers with pppoe and it works but could this be a problem and why!

I have also vlan int. on WAN for menagement !

Can you help me troubleshoot this problem ?
