As of a recent 2014 commit, the dhcp command will always request a new lease from the dhcp server. If you want to use the same feature that was previously supported by set use-cached 1, you only need to use ifopen instead of dhcp to open the interface. The previous IP from the chainload will already be set on the interface.

Hello, can you please tell me, in easy terms, how to fix this problem ?
