[GLLUG] cisco policy based routing vs port forwarding

[Mike Rambo]

Hey all,

I'm wondering if there are any Linux experts out there who are also 
Cisco experts that can educate me on the difference between Cisco's 
policy based routing and port forwarding via iptables on a Linux box.

We have a vendor which wants us to use PBR with their product. The PBR 
method is not working with our 7603 (iOS 12.2) with the vendor having 
concluded it is a problem with the 7603 (which is our core switch and 
has been otherwise fine for years).

As a test, I set up a typical port forward on a Linux box set up as a 
router. That does not work either. The vendor claims that port 
forwarding on this box is not the same thing as PBR on a Cisco and that 
this if the reason why their product will not work.

I'm suspicious of the veracity of this claim. Are there any experts here 
who can educate me. I've spent a couple of hours trying to find a 
definitive answer via the web but have not found much clarity.

Thanks
