That sounds like your router is dropping ICMP from your directors, then.
I'd expect it to take 3 seconds to return, like so:

[graeme@squonk ~]$ ping -c3 192.168.7.254

SELinux doesn't mix well with very much, in my experience, unless you
take endless amounts of time to produce a proper policy for it. If you
can run both your directors and realservers with it switched off until
you get everything running, so much the better.
