Hello out there,
some of my (new) users use MSN Messenger, and since then I discovered a new IP-Lease is my license list: This IP is NOT part of my defined DHCP range, and it regularly connects to rad.msn.com. I also found out that rad.msn.com delivers the ads for MSN Messenger and blocking the internal IP by dropping all packets has no negative effect on MSN Messenger on the clients (except no ads any more, which some might find positive).
But still I'm a little bit worried about that: Why can ASL accept an IP address which is not distributed by DHCP or a pre-defined static one, isn't that a security lag? How can I tell ASL only to accept IPs from DHCP or static routes?
Thanks,
Ontario
