Strange networking issue
The CentOS server does not have iptables on, and selinux is permissive.
With my Win7 server, I cannot ping, ssh, or access web pages served by the CentOS server, unless I do the following:
1. With the CentOS server, I access a web page served by the Win7 server.
2. Then, on the Win7 server, I can ping, ssh, and access web pages served by the CentOS server. But only for a couple minutes. After a couple of minutes, any further attempts to ping or ssh time out.
3. If I then go back to the CentOS server and access a web pages on the Win7 server, I then regain server access from Win7 to CentOS as described in #2, for a minute or two.
Any idea why this might be happening? Or what I could look at which would help solve the mystery?
I switched the CentOS from Wireless to Wired networking and that did not make a difference.
Really appreciate any help. Thanks.

Have you tried disabling SELinux entirely on the Linux system?Sometimes, real fast is almost as good as real time.
Just remember, Semper Gumbi - always be flexible!
