Your statement kept me busy, because the target is not to waste IPs from the
pool. :-)
Director:
(eth0): 192.168.2.10
(eth1) 72.14.147.10
(eth1:0) 72.14.147.200 (VIP)
ipvsadm -A -t 72.14.147.200:80 -s rr
ipvsadm -a -t 72.14.147.200:80 -r 192.168.2.11 -g
Real:
(eth0): 192.168.2.11 (RIP)
(eth1) 72.14.147.11 (from ip pool)
default gw 72.14.147.1
iptables -t nat -A PREROUTING -p tcp -d 72.14.147.200 --dport 80 -j REDIRECT
--to-port 80
Works perfect.
Now i reduce.
1)
I remove the IP from eth1 on the real server. As expected i lose the access
to the default gateway. OK.
2)
Something like that does not work either:
ifconfig eth1 0 up
route add -host 72.14.147.1 dev eth1
route add default gw 72.14.147.1
3)
I change the default gateway to the one responsible for the private network.
Since it does NAT and does not allow to pass traffic otherwise, it does not
work either.
4)
I guess i have either to change the rules on that gateway, so it does pass
traffic "from VIP to internet" without NAT.
5)
Or i create a new private network, which works on eth1 and having a gateway
there, which passes the traffic.
I dont give up yet!
(and iam not google, just used their IP as an example)
