I concur with Munroe. I maintain https://github.com/jsumners/ucarp-rhel7 for my HAProxy failover setup. My guess is that your opposition could stem from multiple OSes not supporting this sort of socket binding. Some quick searching shows me that at least FreeBSD supports it via the “IP_BINDANY” options http://fxr.watson.org/fxr/ident?i=IP_BINDANY. On Linux it is is “IP_FREEBIND”. These are defined in netinet/in.h and netinet/ip.h, respectively.
I think this would be a good feature to support since, as far as I can tell, routers don’t typically allow defining a backup “ip helper.” On December 14, 2017 at 3:04:25 AM, Francis Dupont ([email protected]<mailto:[email protected]>) wrote: Kea is like 99.99% of network servers I know: it binds only to local addresses as required by the standard socket API.
