Can anyone sum up an ipsec VPN for an idiot? Someone asked me yesterday to email them how it works, including a bried explanation of public IP addresses, why we put a private IP in as a DNS server option and... basically explain the tunnel from end to end in simple terms, like;
LAPTOP (PUBLIC IP) |>>>>>>>>>IPSEC TUNNEL>>>>>>>| (PUBLIC IP) ROUTER (PRIVATE IP) | (PRIVATE IP) SERVER
I tried but my brain is melting.
site to site or client to site ?
client to site.
how much detail do you want - do you want to include SA, key exchange, encryption domains ?
