    Hello,
    I am looking on the Internet and manuals, but maybe you can address me
    quickly on the right feature.
    I was wondering if it is possible to configure a router Cisco so that
    it intercepts the events of TCP connection establishment between two
    hosts (SYN/ACK/SYN-ACK sequence) and notifies a remote server passing
    to it the information of the IP header (via HTTP, SNMP trap,or others)
    of the connection.
    Also, is it possible to programmatically add/remove firewall rules on
    the fly ?
    All that I want is to be notified when a connections is established
    and eventually block it on some cases.
    Thanks for your help,
    LB

    LB - You may be able to accomplish the first problem by using TCP
    Intercept. It will somewhat manage the TCP connections from IOS...but
    I'm not sure about the notifications. You might want to check to see
    if you can pull the data through logging or SNMP.
