How do I source an ICMP ping echo from virtual server IP?
I have a virtual server on an LTM with an IP of 10.5.42.115. It is communicating over an IP sec VPN tunnel to a customer in AWS. The VIP is the only host in the encryption domain (SA) on our side. AWS cannot initialize a VPN, they only respond. Therefore when the tunnel times out I have to send them a packet from 10.5.42.115 to bring the tunnel back up. I have a loopback on a switch behind my ASA (VPN endpoint) with 10.5.42.115 assigned to it in a down state. When the tunnel goes down I have to no shut the loopback and ping a server on their side to bring it back up. I then have to no shut the loopback so that the traffic actually gets to the F5. I have to imagine theres a way the F5 can resolve my problem. I am thinking an iRule.
TLDR: I need to send an ICMP echo ping from a virtual server IP address periodically to keep a VPN tunnel alive.
