jails and multple interfaces

[Jeffrey Williams]

Hi Folks,

I am trying to set a jail hosting server to support multiple jails for 
development testing.

The server has two network interfaces, I am configuring one for host 
server to use, and the other with several aliased IPs, one for each of 
the jail servers.

All the services running on the host are configured to bind to the host 
IP on the first interface.

The crux is both interfaces on the same network, I am seeing the 
expected arp errors (e.g. kernel: arp: x.x.x.x is on int0 but got reply 
on int1), now I know I set the sysctl variable 
net.link.ether.inet.log_arp_wrong_iface=0 to get rid of these messages, 
but what I want to know if there are any other problems I am going to 
have having both interfaces live on the same network.  Also even though 
I have the jail host's services all binding to the first interfaces ip, 
there is not guarantee that network traffic originating from the jail 
host will only use its primary interface/IP, is their anyway to ensure 
that the jail host does not try to talk through the interface being used 
by the jails?

Thanks
Jeff
