Identd (resp) port 113 problem on Openview

[menace212]

I have issue with HP Openview attempting to gain access/poll to a machine on the network(security machine). I don't want Openview to poll or even see this machine..Openview is using the ident(resp) protocol 113 to attempt access to this machine. How can I stop this from happening...Should I put a acl on the router preventing access to that machine via ip and port number. Any suggestions.

P.S. This machine is on the same subnet as the other devices in the network.I just want to isolate this machine while not affecting the other machines.
