We are providing cable net connections (wireless/fibre cables) in our town.
in the past we use LISP server. now we are using Microtek. Recently we are getting too many I.P/Mac addresses in ARP list. as you know it means two systems are sharing same I.P/Mac. Concerned authorities said to install firewall in all the clients P.cs its impossible but we did for some but still the problem is not solved. is it firewall problem or anything? anybody knows solution? please help. how can we rectify this problem.
