Hi,
I run two FreeBSD 12.2 servers with haproxy 2.0.22 in a CARP setup.
The frontend-interfaces have multiple IPs and I need to have this
statement in at least one backend service:
source 192.168.185.29
This is because the target-service has some whitelisting for this
specific address.
This has worked well over several years, however recently (maybe with
the upgrade to the 12-series - I can't be sure), it seems that haproxy
on the CARP BACKUP cannot use this configuration anymore - which, upon
closer look, is not totally unreasonable and technically correct.
I assume, previously it would just ignore the statement and use the
interface IP.
I've now commented it out on the slave, but it's a bit silly to have to
remember to "fix" the slave manually on switch-over.
Is there a way to get haproxy to just ignore the source-statement if it
can't use that address for sending (which it obviously can't, when it's
not MASTER)?
