I'm trying to setup a DNS LVS like this: Server A: x.x.x.10 Server B: x.x.x.11 Server C: x.x.x.12
The VIPs are also in the same network x.x.x.2 and x.x.x.3, they are respectively assigned to A & B, or both of them to one via heartbeat if the other server is down. LVS is setup to distribute requests between the three servers. This is working fine. The problem I'm getting is that the reply comes back from the wrong source with the real IP address of A, B, or C, with the "unexpected source" error. I was presuming that I could SNAT this problem away, but it appears that SNAT does not work if the destination is on the same subnet? iptables -t nat -A POSTROUTING -p -udp --dport domain --destination x.x.x.11 -j SNAT --to-source x.x.x.10. My question is whether my real IPs need to be on an entirely different subnet for this to work (that routes through the same box with the VIPs)? Is any possible way of doing this the way I've got it setup or is my initial design flawed? Thank you. _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-requ...@linuxvirtualserver.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users
