We have an old HP server which is running a legacy application. Every now and then the network interface will totally freeze. Our support provider says it is because of stray traffic or somebody running a scan on the IP address. Running any kind of network discovery tools or port mapper against the server will cause the interface to freeze.
We are careful about what we run against it but now and then corporate submits a scan looking for unauthorized computers/software and kills the interface.
It was suggested that we place it behind a firewall / proxy and block all but the required ports to see if this would help.
Has anyone tried anything like this? It would be great to place something inline so we would not have to change any IP addresses.
