Router configuration

In case of a VPN IPSec not between two IPBrick's but between a IPBrick and a router, at the router side it's important to know all parameters used by the IPBrick that are transparent to the web interface. Here are the most important ones:

• Negotiation key protocol: IDE;
• Negotiation mode: Normal;
• Fase 1 encryption Algorithm: 3DES;
• Fase 1 authentication Algorithm: MD5;
• Fase 2 encryption Algorithm: 3DES;
• Fase 2 authentication Algorithm: SHA1;
• Key Group: DH2;

$\Rightarrow$ Note: Before configuring a VPN connection, PPTP, IPSec or SSL, you have to know what is the addressing system used by the local network where the client connects and what is the destination network addressing system. If there is the same addressing system in both networks, obviously the VPN connection will be impossible.
