Hi guys, I'm trying to get a DR setup going with the director being on the same network as the backend servers. The setup is similar to the first example on this page http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.LVS-DR.html although I am anticipating that the clients may not be on the same network. The example is a bit confusing having a router between the client and the LVS setup and still the client's IP address (192.168.1.254) is part of the same network segment (192.168.1.0/24). Anyway, the problem I see is that the director fails to put out the packet with updated MAC addresses back on the network when the client is not in the same network segment.
TCP 192.168.1.161:80 wlc persistent 50 -> 192.168.1.151:80 Route 1 0 0 VIP: 192.168.1.161 RIP: 192.168.1.151 DIP: 192.168.1.122 CIP1: 192.168.1.254 CIP2: 192.168.50.254 Running tcpdump on the director shows the packets from the client coming in, but nothing gets put back out by the director to be consumed by a real server. 0 client2-MAC > director-MAC, ethertype IPv4 (0x0800), length 74: CIP2.46145 > VIP.80: Flags [S], seq 1211711751, win 29200, options [mss 1460,sackOK,TS val 23155864 ecr 0,nop,wscale 7], length 0 1 client2-MAC > director-MAC, ethertype IPv4 (0x0800), length 74: CIP2.46145 > VIP.80: Flags [S], seq 1211711751, win 29200, options [mss 1460,sackOK,TS val 23156114 ecr 0,nop,wscale 7], length 0 4 client2-MAC > director-MAC, ethertype IPv4 (0x0800), length 74: CIP2.46145 > VIP.80: Flags [S], seq 1211711751, win 29200, options [mss 1460,sackOK,TS val 23156615 ecr 0,nop,wscale 7], length 0 When the client is on the same network segment as everything else, it works as expected: 0 client1-MAC > director-MAC, ethertype IPv4 (0x0800), length 74: CIP1.48024 > VIP.80: Flags [S], seq 331779670, win 14600, options [mss 1460,sackOK,TS val 298543355 ecr 0,nop,wscale 4], length 0 0 director-MAC > realsrv-MAC, ethertype IPv4 (0x0800), length 74: CIP1.48024 > VIP.80: Flags [S], seq 331779670, win 14600, options [mss 1460,sackOK,TS val 298543355 ecr 0,nop,wscale 4], length 0 ... Any ideas what the problem might be?
