Routing Issue
I am not much of a Cisco guy but I am at my wits end with a vendor that we have. He has been coined "blue cable boy" by myself since he decided to plug into my PIX during the middle of the day since he didn't know the pasword to it (for good reasons too). Needless to say he took down Internet connectivity and from what I found in the firewall really made me upset. Rules allowing traffic from any host on any subnet into my network, that was his method of troubleshooting things. Then he left those rules in after he was done screwing it up. For the benefit of his health he does not want to set foot on the premises.
Right now my problem is that traffic from my wireless vlan (10.11.x.x) is going through my layer three switch and can hit the internal interface of my PIX firewall. That is where everything stops. Traffic on my data vlan is passed through just fine.
Basically the network structure contains my vlans that go into a Cisco 3750 for routing. Then any Internet bound traffic is sent to my PIX and then outside. The data vlan has a 10.0.x.x subnet and the PIX is on that subnet. The gateway for the 10.0.x.x network is the 3750 with an IP of 10.0.0.254. The other vlan subnets use the same device for the gateway, typically with an IP of x.x.x.1.
My wireless vlan is on the 10.11.x.x subnet and can only ping the internal interface of the PIX, nothing is passed through. Trace routes stop at the internal interface. I did find a rule for ip routes and changed the gateway from 10.0.0.254 to 10.11.0.1 to no avail. I think I am close to getting this fixed and feel that the answer is right in my face. With the time I have into this and my frustration level, I figured an extra set of eyes or two might help.
Here is the config from the PIX with site specific data redacted.
