Question

Possible to have static secondary address on DHCP primary?

Hi all, I'm running a 60D with 5.4.1.  Is it possible to have both a fixed address and DHCP address on a given interface?  I have an upstream ISP who wants to give me an assigned address range to use as VIP's or internally, but DHCP on my interface to them (WAN1).

    i don't think that's possible.

     

    1> when you have a primary ipv4  and then enable secondary, the secondary does not allow for  DHCP client 

     

    2> when you have mode dhcp on the  primary  the  secondary option is not doable

     

     

    Why can't  the ISP just route the "new address" block to your existing  WAN interface ipv4 address?

    I agree with emnoc - I just wanted to add that if you use DHCP on the WAN interface, you can define a VIP with 0.0.0.0 and it always uses the assigned IP on the interface (if it's dynamic). But I'm not sure how you could handle more dynamic IPs with VIPs

    Ah, I think the 0.0.0.0 VIP would work, I only need one inbound port.  Thanks!
