BandNew PIX 515E issue

I've received a few new PIX 515E security applicances and I'm have layer 2 issues on all that I've tested. I installed a small 5 port switch on the inside and cannot ping anything from the console. I have a computer on the switch and it's able to ping other devices on the switch but not the PIX.

What I find odd is that when I try to ping the inside interface on the PIX from one of the inside computers, the PIX shows the MAC address of the inside computer in the arp table.

My goal is to upgrade the PIXs to ver7.0 but I can't do that until I can resolve this issue.

Here is some of the info from one of the PIXs.

#sh ver

Re: BandNew PIX 515E issue

Hi M8,

Your firewall has an FO license, you need to make this unit active to be able to see it.

Run the command:

failover active

With this command, the unit turns into the "Active" state from a failover perspective. It will work after that.

Cheers.

Re: BandNew PIX 515E issue

You`ll have to allow it.

icmp permit 192.168.1.0 255.255.255.0 echo inside

icmp permit 192.168.1.0 255.255.255.0 echo-reply inside

Be careful with you acl_out:

1) would recommend to rename it to inside_in

2) used access-group on IF inside ?

3) be sure to allow more traffic in your acl_out than icmp cause everything else will be automatically denied (implicit deny)

Re: BandNew PIX 515E issue

Ok, I removed my access-list and access-group from the config. Added the "icmp permit" statements and I still can't ping. I've tried changing the interface from 10Baset to 100Baset to 100Full. I can see that the interface is changing by the lights on the switch but none of the devices can ping the firewall. Also I can't ping anything that I add to the switch. Yet, all the devices can ping each other and are communicating.

Re: BandNew PIX 515E issue

Ok lets start with basic,

1 subnets are all the same correct

2 the switch is not mac filtering

3 the switch is all on the same VLAN

4 if you ping from the firewall to machine do you see the mac address in the arp table

5 is the right port with the right access-list and right port on switch.

6 if all else fails set up a capture

access-list cap1 permit icmp any any

capture cap1 access-list cap1 interface inside.

sh cap cap1

you should be able to ping the gateway on the network that the machie connects to, but to my knowledge not through it to another interface on the pix but i may be wrong.

Hope this helps

Re: BandNew PIX 515E issue

Hello Salem,

Thanks a bunch. I thought I had typed that command in the box already. I tried it again and the PIX is working now. I can ping out of the PIX and at the PIX.

Thanks for the help.

Chris
