Sample Configuration
Suppose that the routers SOHO (the local router) and HQ (the remote router)
described in Chapter 3, Installation and Setup are to be configured to use PPP DES
encryption. To add encryption to their configurations, you would enter the following
commands:
For router HQ:
-> remote setencryption dese rx 1111111111111111 SOHO
->
remote setencryption dese tx 2222222222222222 SOHO
->
save
-> reboot
For router SOHO:
-> remote setencryption dese tx 1111111111111111 HQ
->
remote setencryption dese rx 2222222222222222 HQ
->
save
-> reboot
Remember that the transmit key (tx) of SOHO is the receive key (rx) of HQ. Inversely,
the receive key of SOHO is the transmit key of HQ.
NOTE:
The configuration must be saved and the router rebooted (save and reboot
commands) for the encryption to be activated.
Diffie-Hellman Encryption
With Diffie-Hellman encryption, each router has an encryption file that is associated
with a public key providing 768-bit security. The predefined keys can be replaced by
the user. By convention, the key files have the suffix “num” (e.g., dh96.num).
Configuration Commands
To configure Diffie-Hellman encryption, add this command to your standard
configuration:
-> remote setencryption DESE_1_KEY | DESE_2_KEY [fileName]
<remoteName>
