Internal server to VIP from other than Internal subnet
I'm curious, if it is possible to have servers behind the internal BIG-IP vlan to access the VS (VIP) that is either from the External BIG-IP subnet (same as the external vlan self-IP) or other subnet that exists on the BIG-IP (other than external or internal subnet).
server is on the internal subnet 10.10.10.0/24 (big-ip self-ip 10.10.10.51)
VS1 in on the external big-ip subnet 192.168.1.80 (big-ip self-ip 192.168.1.51)
VS2 is from the subnet other than the above (for example: 172.16.16.80)
I was testing (open a webpage) such a configuration in LTM-VE, but i was not able to access the VIP successfully unless I have defined a STATIC nat for the server. I was getting RST packets from the BIG-IP, however the ping to both VIPs was successfull.
Is the behavior different if the server (working as a client) is not directly from internal big-ip subnet but other subnet reachable via the Internal big-ip vlan ?
