I was not able to find a solution for my issue, so who better to ask than Cisco community.
I am setting a PRTG monitoring system in my company and one of the requests is that we ping 4-5 our internal servers from PRTG Server that is located in Ireland. This way we know that we are reachable from the outside.
When I create a "Cloud Sensor" in PRTG I get the following error: "TCP Ping on port: 80 timeouted/port is closed".
It is my understanding that I need to create a rule and let the TCP ping from the IP address of the PRTG server in Ireland to our servers. The problem is I AM NOT A FIREWALL GUY. I do not know how to do this. I know how to create a rule (yey) but what to enter in it - that is the problem. I dont know if the rule should be outside or inside, the list does not say "TCP Ping" in the rule.
We are using Cisco ASDM 7.7(1)151.
Is there a good soul that can really create a simple walktrough having in mind that I am a noob in this?
