NacreousHello,
If you can reach the F5 or the F5 can reach all required resources without any default gateway, it's fine, no need to add a route. Otherwise, you will need to add a default route on Network >> Route or using a tmsh command :
create /net route 0.0.0.0/0 gw 30.99.99.254No need to take care of the route domain. If you don't specify any route domain in the route configuration it's a route used within route domain 0.
Sarah_258804I am able to reach everything that I need to from the F5, but how do I know which interface it's communicating on? I want to be sure it's not relying on my management IP address.

If its the reply (for a client hitting a virtual server f/e), then f5 using the Auto Last Hop feature. Nor replies it wont use the management interface.- Yann_Desmarest_Simple, if the destination you try to reach is directly connected to the F5 by a Self IP, it's fine. If you are able to reach a destination that is not directly connected, the traffic probably use the management port. To make sure, you can launch a tcpdump command on the cli and see if there is traffic outgoing to the mgmt
- Yann_Desmarest_You can use the following : tcpdump -s 0 -vvv -i eth0 host your_destination_ip
