I wonder if anyone has experienced what we are seeing on
a couple of low cost isps?
We see multiple echo request packets from the network...sometimes more than 20 and then port 135 dce endpoint resolution request packets...Our software echos the icmp echo request packets and sends a reset packet to the dce request but it just doesn't shut them off. At times these packets just take all the bandwidth from the connection and we are unable to access pop3 or send mail via smtp. There are also a few igmp group member request packets but they don't seem bothersome(we just ignore these).
We have a third isp that sends echo request packets and when we echo back the packets are not sent again, which I thought should be the behavior...this particular isp does have a problem in that it frequently issues an unreachable icmp packet, which pretty much ends the connection.
Which leads to my specific questions:
Are these isps just totally bogged down?
Why are they sending these packets?
Is there any solution aside from getting another isp?
Welcome suggestions for well behaving isps.
Thanks in advance.
