Hi,
I'm using LVS/DR for my Mail system. With Redhat 7.3 machines acting as
Director's for a cluster of FreeBSD SMTP servers using Keepalived for HA
and service monitoring.
Ok.
Recently updated one of the SMTP server to from 4.7-stable to
5.0-current and found that LVS/DR works with FreeBSD 5.0-current as long
as ip forwarding is enabled.
I do not believe that it has changed. So something else has changed if it worked
before or you had ip_forwarding=1 before too.
Please convince yourself that the /etc/rc.network in FreeBSD 4.7-stable is the
same as with the current CVS:
http://makeashorterlink.com/?A4A823F73
This can be done 2 ways.
in /etc/rc.conf
gateway_enable="YES" # Set to YES if this host will be a
gateway.
by manipulating a kernel state directly via sysctl
sysctl net.inet.ip.forwarding=1
The first yields the latter. So in fact there is only one way. What would be
more interesting is, why you need ip_forward on a backend server. Check your
settings in /etc/defaults/rc.conf or make a diff to the 4.7 one. There were
changes related to sendmail defaults in this file lately.
Best regards,
Roberto Nibali, ratz
