- Ok Guys, I could figure it out that was gateway missing on real servers. I'm just testing it now. Something I've noted is that sometimes " timeouts " with a specific request (opening a html link for

- Yes, I've said about RPF, but I think I should see the packets "trying" to go out I guess. I'll give a try using NAT, because at my first try it didn't work either. I get back to you this morning yet

- As far as I know, rp_filter is on the input side: it drops a packet if the hypothetical reply packet *would* go out on a different interface to the one the packet arrived on. Thus it must be switched

- Maybe, But rp_filter just controls where the reply packet goes, default setting is out of any interface (which I've always thought is a bit crazy). I would start with a one arm one VLAN configuration

- I tried both, but it didn't work. Maybe my switch/gw is rejecting packets from my realservers directly to customers because of RPF filter? 2014-03-24 18:03 GMT-03:00 Malcolm Turnbull <malcolm@xxxxxxx

- I've never used that method before, I would think you would need to be careful with your rp_filter settings? The ones I know that do work with the DR mode LVS arp problem are: http://pdfs.loadbalance

- Tiago, Is the apache server responding to BOTH the RIP & the VIP? (RIP for health checks, VIP for load balanced traffic) And how have you solved the ARP problem for the loopback adapter? -- Regards,
