Help with removing network ACLs from F5 which were made with iApps (f5.data_center_firewall Template...)

I've not heard of any tool that would automatically do this. The Packet Filter feature of F5 is similar to very basic ACL's. Virtual Servers are listeners, so you need to have a listener ( for example, on 0.0.0.0 which would listen for everything), then packet filters locks them down. More info here. http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip9_4mgmt/BIG_IP_9_4_nsm_guide-13-1.html

They should have just turned on F5's AFM module which is a firewall and they wouldn't have needed a separate Firewall and it would incur much less latency. :)
