Stop Network Traffic from a Particular host.

We are seeing some network trafiic coming to a server (A) from a Server (B) which we are not expecting. Is there a way we could stop the traffic flowing from that particular host? Server A runs redhat 6.3 Server B runs redhat 5.9. This is preventing us from testing the application as we see unwanted traffic. when i do tcpdump -i bond1 for 3 minutes, about 90% of traffic is from server B, which we do not want at all and is not even related to our App. Is there a way we could stop this traffic anyway from redhat configuration?

One of the ways we test application is by doing tcpdump -i bond1, while we do that we see about 90% of traffic generated from server B. If we do grep for that host we see most entries for that Server B which we are not expecting. I wanted to find out if there was a way we could stop this either by xinetd with no_access etc. Is there a way to block this host's network traffic?
