Releasing external DHCP assigned address

JimmyM
I've been trying to figure out if I can release the DHCP assigned address my ASG gets from my ISP (Verizon FiOS). I've read here that I can do "ifconfig eth0 down". But that just takes down the interface. It doesn't send the DHCP_RELEASE command required by my ISP to actually release the ip lease.
I've also read that I can do "dhcpcd -k" and THAT will send the DHCP_RELEASE. But if I navigate to /var/chroot-dhcpc/usr/sbin and do "./dhcpcd -k" I get a message that no interface was given. If I do "dhcpcd -k eth0" I get a message that dhcpcd isn't running.

So what is it guys? How can I take down my external interface AND send the DHCP_RELEASE command?

    Jimmy,

    One other necessary item. I use the Actiontec router as a MOCA to Ethernet bridge only. On the Astaro it was necessary to add a rule allowing the Actiontec outbound access(Actiontec>Any Service>Destination Any IPv4). In the absence of the rule VOD will not work in this configuration. 

    Thanks,
    Jim

    Scottj,
    I'm not using IPS though.
    I had been using an NIM100 as the MoCA/Ethernet bridge and that was working very nicely. I had an interface dedicated to the NIM100 and had everything working nicely. It was just the pixelation causing the issue. I even had the Remote DVR working.

    I just checked and UDP flood protection is turned off. Perhaps I should start another thread regarding the pixelation.
