I've been trying to configure phex to communicate only with a certain list of IP addresses. That is, I'm trying to get phex to only work with a whitelist of IPs.

I tried the following security rules:

DENY network mask 0.0.0.0/255.255.255.255
ALLOW network range x.x.0.0-x.x.255.255

However, after applying these rules, I'm still able to connect to servers outside the allowed IP range, and I'm also to download from hosts outside of the range.

Could someone please tell me what I'm doing wrong?

Thanks.
