Hi,

I was listening to a podcast today about VPNs, and it said that the 'plain text' packet is wrapped in a VPN packet and then encrypted via IPSEC with ther source and destination IPs encrypted as well. My question is, if the destination IP is encrypted how does the packet get there?


thanks

Susan,

My understanding is that the destination IP of the packet that is embedded is encrypted, but the destination IP address of the VPN packet itself isn't encrypted (The payload of the VPN packet is another packet, and this whole payload is completely encrypted but other parts of the packet are just like any other normal packet). But again, IANASA (I am not a Security Analyst)

PS: Was this on Steve Gibson's Podcast? That one is so much fun.
