I currently connect the Firewall to one Cisco layer 3 Switch which has 2 VLANs, one for outside and another for inside.
When I try to show arp table on the switch, the arp table to inside host is not always there. So every session initialed by other host has to send a ARP broadcast.Is it normal? How can I improve this issue?
Also, maybe it's coincident, on the SQL connection, the client host always generate the NBT query after the prompt TCP handshake. After 3 times failure in attempt, the session is setup. But it takes more than 3 seconds unnecessarily on NBT query. I am not sure this is something related to Cisco Swtich or Firewall. Can anyone advise?
