Force IP renewal on Cisco 837


Belgacom ISP force IP renewal for their residential ADSL customers every 36 hours for whatever stupid purpose (annoy us, sell their fixed IP option, etc.).

Here’s how I force my Cisco 837 router to renew its WAN IP every night at 01:00am :

<code>kron occurrence RENEW_IP at 1:00 recurring
 policy-list RENEW_IP

kron policy-list RENEW_IP
 cli clear interface Dialer 1</code>

I’m less likely to lose my SSH/VPN connections now..

Thanks for reading this post!
