The problem is that routing fails. This might not be in the router, but maybe related to another component on the internal network.
Here is the problem:
Connections to the web server timeout. There seems to be no pattern to when these timeouts will occur. I need to get rid of these timeouts.
I have been able to setup a continuous ping to the web servers and the timeouts occur at the same point when the ping fails.
Additional Network Information:
Continuous ping from the internet to the external port on the router does not fail.
Ping from the router to the web server does not fail.
Ping from the same internet location to the web server eventually fails.
The topology is Internet < -- > Router <--> Switch <--> Web Server
I am not sure what is causing this, it might be the router, the web server or a third piece of networking equipment. I have done some testing, but will do additional testing as requested.
