NimbostratusHi Rajagopal,
I changed my config and it worked! Thanks for your reply.
In linerate it should use the interface ip address for virtual server ip.
But in F5 LTM it could uses ip address on the same subnet of the interface ip address.
I should change my mind to use linerate.
- Yes, exactly, the BIG-IP LTM behavior is very different from LineRate with respect to virtual address traffic handling configuration. In LineRate, an Interface address + VirtualIP + VirtualServer together define the reverse-proxy data path from a client to the LineRate system (with a Real Server configuration attached to a VirtualServer defining the back-end of the proxy). You might think of this as Layer2/3 + Layer3/4 + Layer4+ components of the application proxy: the interface (Layer2) configurations allows the network to resolve the L2 MAC address for the IP address (Layer3); the VirtualIP attaches an L3 network address and L4 port of socket to a VirtualServer. Also note that ICMP behavior may be different than you expect. See http://docs.lineratesystems.com/093Release_2.5/100Getting_Started_Guide/100LineRate_OverviewICMP for specifics. Hope that helps!
