Hi,
I have an isolated network (192.168.3.x/24) being served by VirtualRouter,
where 10.84.59.131 is SourceNAT address
and eth0 is VN interface of VirtualRouter & eth2 is the public interface of
VirtualRouter.
When I look at the nat table entries on the VirtualRouter, it shows following :
root@r-6-VM:~# iptables -L -t nat -n -v
..
..
Chain POSTROUTING (policy ACCEPT 330 packets, 22113 bytes)
pkts bytes target prot opt in out source destination
0 0 SNAT all -- * eth0 0.0.0.0/0 0.0.0.0/0
to:10.84.59.131
--> Why the "out" interface for the SNAT entry is VN interface (eth0) instead
of Public interface (eth2) ?
I'm using "Cloudstack Release 4.3.0 (64-bit) Thu Apr 10 20:27:11 UTC 2014"
cloudstack-release template.
Thanks,
Sachin
