DHCP renewal is quite agressive

[bingo600]

This is a minor issue , but logs a lot.

Seems like PP DHCP client tries to renew every minute instead of on "Half lease time"

Code:

DHCP works fine , but i get a lot of notifications like this in logwatch mails

Code:

reuse_lease: lease age 3910 (secs) under 25% threshold, reply with unaltered, existing lease for 10.14.60.161
