So... you have multiple advertising routes, and each box has 5 public addresses, and the complaint is that the boxes can't magically decide how to handle all of the different routes?
When it comes to routing, you have two options, delegate or self-manage. In the case of self-management, yes, if you want complex route management, then you'll need software that handles complex route management.
Why not use Stateless DHCP, and configure a machine with short leases that can update the others as needed? It can handle the complex routing, and the clients just have to frequently ask if there are updates.
- yardstick 8y agoIn 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
