Forwarding IP VS
When we first implemented APM for SSLVPN remote network access, we were told we needed to forwarding virtual server to allow the VPN clients to route back out to the Internet through the F5. A route was built and a fwd VS was set up that looks like this.
Type: Forward IP Source: any Destination: any All ports All VLANS Auto Map
Our BigIP's sit at the edge of the network connected to the router, not behind a firewall. My concern is that anyone can bounce traffic off the external interface of the BigIP with this VS enabled and proxy traffic from that external interface IP address. Am I understanding this correctly? In addition, wouldn't a better implementation be to just set a default route for the clients to go out our firewalls so they hit the rest of our security infrastructure for inspection of the traffic? Or is there a better way to limit the forwarding virtual server to only the clients in the network access lease pool?
Thanks for any input.
