Cisco 515e PIX Firewall: Route only port 80 and 443 traffic
Posted on 2008-10-24
I have a PIX 515e firewall with 3 interfaces (Inside, ISP_1, ISP_2). I currently have everything routed to ISP_1 but I would like to route all Web Browsing traffic (port 80 and 443) to ISP_2 and all other traffic continue out ISP_1.
I have setup an ACL specifying all traffic going to 0.0.0.0 on port 80 and 443 to use ISP_2. But for some reason when I do that, that ACL rule reverts back to ISP_1. I am using the PIX PDM GUI.
Also, I do not have a static route defined for the ISP_2 interface, only an ACL. I am not sure how to define that route since I already have one ISP_1. Would it be somehthing like this?
<local network> <Local subnet> route to <ISP_1>
<local network> <Local subnet> route to <ISP_2>
I am not sure how the above would work. I still want all non port 80 and 443 traffic to go out through ISP_1.
Your help is appreciated.
