Michael-

Not knowing your setup, I can only speculate but if you are using Exclude IP directives for authentication and a VPN to allow access from the outside of the IP range registered with the vendor, the VPN must be set up to route all traffic through it, not just the traffic destined for the Campus LAN.

It will increase the traffic that the VPN sees to include the “other” places that users may roam but will keep the subscription communications going through the correct networks.

What happens is that you are authenticated because the address that the VPN presents to the EzProxy is an internal address.  The Exclude IP directive removes the EzProxy from the conversation from that point on.  When this happens, you get authenticated but then the consumers browser then talks directly to the vendor.  This is usually what gives you the non-routable, internal addresses.

Hope this helps.  Good Luck!

Please forgive my ignorance here - We are trying to figure out why our Books24x7 links are not working and the vendor did an IP analysis that revealed many internal IP addresses – not the ones we share with the vendor. Our network person thinks it is a security risk. Has anyone experienced this?

Thanks,

Michael
