Hello
i have faced an strange problem in my network.
i have a firewall which has 2 interfaces (public interface and LAN interface).
i have set the ip address of LAN interface as default gateway on ly client systems.
some systems occasionally can't access internet & after hours of checking, i founded that in these clients Arp table (shown with Arp -a),
the IP address of firewall's LAN interface is shown with a wrong MAC address (the MAC address of public interface of that firewall). !!!!
after we disconnect & reconnect network cable on these clients or after disabling & enabling client NIC, now the correct MAC address is shown in Arp table.
any help please ?
(additional info : firewall is kerio control version 9, installed in a VMware ESXi virtual machine).
(All settings are done prfectly & no false setting in ESXi or Kerio)
