Can't ping PC from PIX515

nateleduc — Mon, 11 Mar 2019 23:19:30 GMT

I am unable to ping my computer (attached via crossover). I can ping from the PC, but not from the PIX515. I'm using ethernet 1, and I have its IP set at 192.168.1.2/24, but for what ever reason I am unable to contact the computer. I tried messing with the access list a little bit but nothing so far.

Can't ping PC from PIX515

Pls kindly add the following:

icmp permit any inside

Also, does your PC have any firewall that might be blocking ping?

What is your PC ip address and subnet mask?

Thanks for the response.

That did not work either. One weird thing is that even in monitor mode I can't ping, but I can be pinged.

PIX:192.168.1.2/24

PC:192.168.1.69/24

Also my firewall is turned off currently

Indeed weird. If you try to change its ip address to something else, 192.168.1.100/24, does it work? I assume that it only has 1 NIC?

Change what, the computer or the PIX?
Here is my exact output for monitor mode. Computer has a static IP, also its direct connection, no switch in between.

I think my PIX might be defective.

As you can see I tried setting the gateway, just to see if that would help. Also after the first ping failed I swapped to a straight through

looks like port error base on the error message below from your output:

Ethernet auto negotiation timed out.

Ethernet port 0 could not be initialized.

Do you use ethernet 0 or ethernet 1? Can you try the other port?

No, for what ever reason I can't get ethernet1 to comply at all. Here is the output for it:

I thank you for the quick replies by the way. Also there is a red LED inside light up. Don't know what that means

Looks like the PIX is faulty, both interfaces can't be initialized.
