3. CONFIGURATION
Do not miss:
• If local and remote subnets are not configured then only packets between local and
remote IP address are encapsulated, so only communication between two routers
is encrypted.
•
If protocol/port fields are configured then only packets matching these settings are
encapsulated.
The following procedure describes how to generate certificates and keys without a pass-
word phrase:
******************** certification authority ************************
openssl rand -out private/.rand 1024
openssl genrsa -des3 -out private/ca.key 2048
openssl req -new -key private/ca.key -out tmp/myrootca.req
openssl x509 -req -days 7305 -sha1 -extensions v3_ca -signkey
private/ca.key -in tmp/myrootca.req -out ca.crt
******************** server cert *************************************
openssl genrsa -out private/server.key 2048
openssl req -new -key private/server.key -out tmp/server.req
openssl x509 -req -days 7305 -sha1 -extensions v3_req -CA ca.crt -CAkey
private/ca.key -in tmp/server.req -CAserial ca.srl -CAcreateserial
-out server.crt
******************** client cert **************************************
openssl genrsa -out private/client.key 2048
openssl req -new -key private/client.key -out tmp/client.req
openssl x509 -req -days 7305 -sha1 -extensions v3_req -CA ca.crt -CAkey
