BIG-IP LTM 6400: Direct access on real servers
Hi,
We've two BIG-IP LTM 6400 in active/standby configuration mode.
We've configured many Virtual Server but we can't directly connect to the real server.
The virtual network is on 1.6 interface and real server network is on 1.8 interface.
Below tcpdump's output on master BIG-IP:
14:48:17.676949 802.1Q vlan240 P0 CLIENT.51704 > SERVER.http: S 2466261397:2466261397(0) win 65535 (DF) [tos 0x10]
14:48:18.581313 802.1Q vlan240 P0 CLIENT.51704 > SERVER.http: S 2466261397:2466261397(0) win 65535 (DF) [tos 0x10]
I only see "SYN" packets and real servers receive nothing.
I enabled "net.ipv4.ip_forward" but I can't go directly to the nodes.
Thank you,
Regards
Daniele
