1771.0. "alarming on links through the firewall" by SNOFS1::NANCARROW () Wed Feb 05 1997 00:42

    I have a desire to monitor our INTERNET connectivity from a management
    station on the clean side of the firewall. Is there anyway to monitor
    this by say allowing an ICMP poll through the firewall to our ISP for
    example or using snmp management from the router through. The only
    secure way I can think of is to get the firewall to ping the ISP and
    somehow get a status back to the management station by ftp or mail.
    Iam open to ideas.

Using screend you can open holes to allow snmp through like
pings, traceroutes etc.

I have done this where a customer used HPOpenView that allowed
them to monitor their net and the the isp link.

Who needs research? ICMP is ICMP (man screend will tell you how to allow 
specific ICMP types through), and /etc/services will tell you which ports SNMP 
uses.
