Strange connection from VIP to suspicious IP on Internet

Hi Armando,

Your going to want to see what server's behind your BIG-IP are trying to access that IP.   Applying a simple iRule will help narrow down and help determine the source.  The IP mentioned has shown up here Abuse IP Check.     You can easily block any connections to that destination IP Blocking IP's

when CLIENT_ACCEPTED  {
    # Log the source and destination IP addresses
     log local0.info "Connection: Source IP: [IP::client_addr], Source Port: [TCP::client_port], Destination IP: [IP::local_addr], Destination Port: [TCP::local_port]"
}
