FreeBSD 5 and LVS

[Ken McKittrick <klmac@xxxxxxxxxxxxxx>]

Hello

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.
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.
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

Sincerely
