hi all .
i came across strange issue -
i have multiple ipsec tunnels on my F5 configured with ipsec interface ips on both ends
all remote ends are fortigate devices -
on all tunnels i can ping the remote tunnel ip with no issue
but i have one tunnel (which is up) that i cannot ping the other sides ipsec intrface
how can i debug this with cli ?
any help with be appreciated greatly
this article has some info, but as the tunnel is up it feels you want to look a step further:
a packet capture showing the traffic enters the tunnel would be best. if it does then it might be the other end (FortiGate) which doesn't respond for some reason. a capture on that side would also be useful to check if it arrives.
