ipsec question

So i have my public interface ae1.10

I attached a ikev2 interface to that and attach it to tunnel.50

no the other side of the ipsec tunnel are providing 192.168.10.0/24 and I am providing 192.168.250.0/24

do I have to place a static route in the v_router saying 192.168.10.0/24 via tunnel.50

how do i do that if I haven't applied a ip address to the tunnel interface, do I have to

do I have to add the static route ?

@Alex_Samad

In IPSEC if you need to reach remote network on other side say 192.168.10.0/24 then you need to put Static route saying

to reach remote network 192.168.10.0/24 interface is tunnel .50

There is no need to apply the IP 192.168.10.0/24 to any PA interface as any traffic for 192.168.10.0/24 will have tunnel interface as outgoing interface and tunnel interface is virtual and it knows it has to pass the traffic to interface with public IP address which in your

case is ae1

PA public IP ---------------ipsec tunnel --------------------------------------------Remote Device Public IP

So because the destination address is part of the proxy, it will route it via the tunnel.

Thought that might be the case.

Thanks

edit

did a quick check remove the static routes and tested the FIB for that destination it wasn't going via the tunnel !

Did a quick test the packets are not going out the tunnel - they are going out the public ae.

so my ae.7 is my internet and I have a few ip's on here. one of them is my end of the ipsec ike
