Public bug reported:
Now we just support floating ip for DNET and SNET. But we don't support port
mapping .
I think we can add a extension param "port" to the floating ip add allowed the
same floating ip with different port associate to different local ip.
For example:
We have two vm192.168.1.10/192.168.1.11, one for Web server, another for
Ftp server. We need to use the same external ip address a.b.c.d to connect this
two server with different port.
Then we could use:
iptables -t nat -A PREROUTING -d a.b.c.d -p tcp --dport 80 -j DNAT --to
192.168.1.10
iptables -t nat -A POSTROUTING -d 192.168.1.10 -p tcp --dport 80 -j SNAT --to
192.168.1.1
iptables -t nat -A PREROUTING -d a.b.c.d -p tcp --dport 21 -j DNAT --to
192.168.1.11
iptables -t nat -A POSTROUTING -d 192.168.1.11 -p tcp --dport 21 -i eth0 -j
SNAT --to 192.168.1.1
