PIX515E : Unable to ping interfaces

Dear ALL,

I'v just got a new 515E PIX, 6 interfaces, Version 6.3(5).

I can't carry on any task with my PIX because the most simple operation is impossible: I can't ping the inside interface or from PIX any other host belonging to th same subnet. Interface is up and running, directly connected to a switch, icmp is enable on inside...

Please, anyone of you could give me an help?

Regards

Alberto Brivio

Re: PIX515E : Unable to ping interfaces

Make sure the PIX is not a "Failover" license. You won't be able to ping from this type of box until you enable failover.

Re: PIX515E : Unable to ping interfaces

Alberto,

Are you trying to ping the inside interface IP of the PIX from an XP box? If so, then make sure that the XP firewall is disabled.

Also, from the PIX can you issue: sho arp this should indicate if the PIX is picking up the internal client IP/MAC addresses, you can also try to ping the directly connected clients from the PIX – see if you get a reply.

What sort of cable are you using to connect the PIX inside interface to the switch, is it straight through or cross-over??

It would also be good to see you pix config, if you do post it here please make sure to take out any sensitive info.

Let me know how you get on.

Re: PIX515E : Unable to ping interfaces

Jay,

many thanks for your prompt reply.

At the end of the message you can find the entire configuration.

Answering your question:

I'm trying from XP , fw disabled

from PIX side is the same story, no ping at all, but I can see XP boxes' arp addresses typing sho arp

I'm using straight cables and a switch

Re: PIX515E : Unable to ping interfaces

Alberto,

Mmmm... So the PIX is seeing IP/MAC but you don't get reply from clients when you ping from the PIX! What happens if you connect the inside interface cable (using a cross-over) directly into a stand alone PC or laptop NIC - can you now ping the inside interface IP of the PIX and vice-versa.

Let me know -

Re: PIX515E : Unable to ping interfaces

do "de ic t" on the pix. the output of this debug would provide more insight related to the issue.

e.g.

4483: ICMP echo request (len 32 id 2 seq 25088) >

4484: ICMP echo reply (len 32 id 2 seq 25088) >

4493: ICMP echo request (len 32 id 2 seq 25344) >

4494: ICMP echo reply (len 32 id 2 seq 25344) >

4497: ICMP echo request (len 32 id 2 seq 25600) >

4498: ICMP echo reply (len 32 id 2 seq 25600) >

4499: ICMP echo request (len 32 id 2 seq 25856) >

4500: ICMP echo reply (len 32 id 2 seq 25856) >

Re: PIX515E : Unable to ping interfaces

Alberto, not really related to your question here but in looking at your int configs i noticed you have it set to auto. i believe it is better to specify 100full or what have you based on your switchport settings. also, ssh is safer then telnet. just a suggestion. take care.

Re: PIX515E : Unable to ping interfaces

Hi,

PIX wasn't running because Failover License has been loaded but failover wasn't enable.

I would like use the PIX as standalone machine and not in failover configuration, but is this possible?

In this condition, the following warning appears:

" This machine is licensed as a secondary failover only unit.

This machine will reboot at 24 hours intervals in its current state. "

How can I do to avoid this behaviour?

Any other features could be compromized by this current state?

Thanks to all of you.

Regards

Re: PIX515E : Unable to ping interfaces

failover unit cannot be deployed as stonealone. a licence upgrade needs to be purchased.

Re: PIX515E : Unable to ping interfaces

It is true that you can't use this as standalone in a production environment ( or shouldn't ). If you are using it for a lab environment, just enable failover. The PIX will not be able to establish communication with a fully licensed Pix so it will automatically become active. It will reboot every 24 hours, but for a lab environment, it's not that big of a deal.
