Multiple IPSec tunnels to the same remote peer

Theoretically you could if you had a different source IP on the same device to initiate traffic from but you would have to have completely separate lists so that your device knows how to split the traffic. So this would require a routing policy that would direct traffic down each tunnel for specific traffic and then you would have to have the same on the other end. Typically this is done by having a routing policy that says this source host/subnet will communicate with this destination host/subnet when traversing this tunnel. I do not believe you would be able to have all subnets flow down both tunnels simultaneously because of how routing functions. I did mean same device because typically F5s do not have multiple ISP connections directly connected to them but it is possible.
