In my case, I want to fail over from VDSL to 4G within a couple seconds of VDSL going down. Will short leases cover that?
I also like to load balance traffic on another site with two VDSL links and a 4G backup. I can’t do that without NAT.
- AstralStorm 8y agoLeases? What leases, this is not DHCP. If you mean Route Advertisement with short life, then yes.
- yardstick 8y agoThe leases referenced by the post I was replying to: “Why not use Stateless DHCP, and configure a machine with short leases” How do you deal with one missed RA causing an inadvertent failover to using a different WAN, while maintaining 1-2s failover after the first WAN link goes down? Also this does not fix the issue with inability to load balance without NAT. Eg I have a desktop (or tablet etc) that I want to send VoIP out one WAN and everything else out another.
- dmayle 8y agoDHCP traffic is approximately 512 bytes in each direction for each half lease period. Stick 1000 clients on a single node, with 2 second leases, and you'll use 0.5% of your bandwidth, and be able to update your default gateway every second
