Unable to ping through PIX 501 firewall

Hi Guys,

I am very much a PIX newbie but I have inherited this one at a client site.

I am unable to get a response to ping from the inside network. Ping works fine from the PIX itself.
Config is as follows:

PIX Version 6.1(4)
nameif ethernet0 outside security0
nameif ethernet1 inside security100
enable password ArBRdD0hYbx encrypted
passwd 2KFQdI.2KYOU encrypted

As I understand the line access-list acl_out permit icmp any any echo-reply should be allowing me access.
Could there be anything else causing this?

Ping by name does resolve to ip but still get Request Timed Out

Please can you assist.

Regards

Mark

acl_in is applied to the outside interface, not acl_out:

access-group acl_in in interface outside

Add this:

access-list acl_in permit icmp any any echo-reply
0
lrmooreCommented:

access-list acl_in permit tcp any host "Replaced for Privacy" eq 85
access-list acl_in permit tcp any host "Replaced for Privacy" eq smtp

<== add (as JFrederick29 sugested):
 access-list acl_in permit icmp any any echo-reply

<== You don't need any of these explicit denies unless you want to log. EVERYthing is denied unless you explicitly PERMIT
no access-list acl_in deny ip 0.0.0.0 255.0.0.0 any

no access-list acl_in deny ip 224.0.0.0 224.0.0.0 any

Re-apply the acl any time you make changes:
   access-group acl_in in interface outside
0
lrmooreCommented:
You could just get rid of the acl_in and apply the acl_out since you already have the icmp allows in it...

no access-group acl_in in interface outside
no access-list acl_in
access-group acl_out in interface outside
0
