Asa route to different interface

Hello,

I currently have a very simple setup.  ASA 5520 advertizing a default route to a 4507 switch and one internet connection for all devices.  The asa does the firewalling and NAT.

What I want to do is add a second internet connection to the asa and route, not NAT some of the users to that interface.  This second connection will be a layer 2 network to our isp which is hosting a virtual firewall for us.  So we want all of our internal ip's to hit the private side of this virtual firewall.

That said i want to keep our existing internet connection and all of the current NAT setup on the ASA.

What would be the best way to accomplish this, as I see that the ASA does not support PBR.

Thanks,

Dan.

Hello, Dan.

Not clear what is desired configuration for this second link and do you need any Internet access failover between interfaces, but:

- you could create additional context on ASA and configure it for second link;

- in this case you will loose dinamic routing (not compatible with contexts);

- you won't be able to run one context in routing mode and another in transparent (if you thought about it);

- PBR should be done before traffic reaches ASA (on switch/router).

Do you have any diagram describing current configuration (almost clear) and configuration for second link (including IP-addresses, NAT and routing if present).
