is the routing on the F5 the same as on a router ?

Hello,   I have an F5 and one of its interfaces is configured on a network e.g. 128.1.1.0 subnet 255.255.255.0. On the same F5, I have another interface which is configured on the network 10.1.1.0...

I want a packet to travel from the 128.1.1.0 subnet to the 10.1.1.0 subnet VIA the firewalls.

 

you are talking about traffic from device in 128.1.1.0 subnet (not traffic from bigip itself), aren't you? the device in 128.1.1.0 subnet's default gateway is bigip, isn't it?

 

you can create network virtual server (e.g. 10.1.1.0/24) listening on 128.1.1.0 vlan and use firewall as a pool. so, when traffic matches the virtual server, it will be sent to firewall.

No. I am referring to the configuration ON the F5 of two interfaces e.g. 1.2 and 1.3. Interface 1.2 will have the IP of 128.1.1.1 (belonging to VLAN X, and interface 1.3 will have the IP of 10.1.1.1 (belonging to VLAN Y). These two interfaces are connected physically by a firewall, which has the needed rules for communication as needed. I want to configure my F5 that the packets leaving interface 1.2 go to interface 1.3 VIA the firewall. Question 1) Can this be done OR the F5 will act a router and since it knows that the two subnets belong to the device, it will do an internal packet transfer without going to the outside world (i.e. via the firewall) ? tx Br
