The address we see in the firewall monitor is the S4 interface ip which is a /30 between the S4 and the firewall. The S4 is pinging various ip addresses that are not part of our internal network. The S4 is pointed to the firewall as the default gateway via OSPF. I haven't captured any traffic yet or looked up the destination addresses on the internet to know what the normal traffic is. Just trying to understand what causes the S4 to ping the off network addresses. thanks walt

What other traffic ends up at those destination addresses? That may give us more of a clue.

Looking at a traffic monitor built into our FW it shows the WAN port ip address of our router pinging various internet addresses. Users on all subnets are set with a gateway address and proxy arp is on. Does the router ping to determine the destination address is alive before it responds to an arp? thanks in advance walt w Walt Witkowski Primary Network Specialist - Sungard Higher Education Office of Information Technology - Delaware County Community College 610-359-5017(phone) / 610-359-4123 (fax)/856-217-4430(cell) [email protected] --To unsubscribe from enterasys, send email to [email protected] with the body: unsubscribe enterasys [email protected] ------------------ CONFIDENTIALITY NOTICE --------------- This message, including any attachments, is for the sole use of the intended recipient(s) and may contain privileged confidential information protected by law.
