I am working on PIX.My inside host(10.32.0.64) is going to External address for NTP. I have opened ACL traffic from Inside for ntp on Inside interface. My question is, should I open any ACL from Ex NTP to 188.8.131.52? Please help.
global (outside) 7 184.108.40.206 netmask 255.255.255.0
nat (inside) 7 10.32.0.64 255.255.255.255
