Hi,

I'm building F5 lab on vmware and already follow all step from 382764900-LTM-Fundamentals-Exercise-Guide-Partners-V13-0-K.pdf. Ping and access browser to management was success but i can't ping to virtual server that i made on LTM (state vs already green) from local PC or client windows 7.

Version : BIG-IP 13.1.1.4

Virtual Network Editor : VMnet1 (Host-Only) 10.1.1.0/24 , VMnet2 (NAT) 10.1.10.0/24 Gateway 10.1.10.2 , VMnet3 (Host-Only) 10.1.20.0/24.

Vlan : External 1.1 (untagged), Internal 1.2 (untagged)

SelfIP : 10.1.10.240 (external) and 10.1.20.240 (internal)

Is there any step that was i miss?
