icmp weirdness - PIX 501 (does any really mean any??)

anyone care to take a poke at this?

pix501(config)# sh access-list out_in access-list out_in; 5 elements access-list out_in line 1 permit tcp 192.168.4.0 255.255.255.0 interface outside object-group TCP-21-THRU-137 access-list out_in line 1 permit tcp 192.168.4.0 255.255.255.0 interface outside range ftp 137 (hitcnt=0) access-list out_in line 2 permit udp 192.168.4.0 255.255.255.0 interface outside eq netbios-ns (hitcnt=0) access-list out_in line 3 permit tcp any interface outside eq 24 (hitcnt=0) access-list out_in line 4 permit icmp interface outside any object-group ICMP_REP access-list out_in line 4 permit icmp interface outside any echo-reply (hitcnt=0) access-list out_in line 5 deny ip any any (hitcnt=13) pix501(config)#

ip audit signature 2000 disable

here is the syslog entry from when I ping 64.233.167.104 from

192.168.50.7

Sep 23 03:08:43 pix Sep 23 2005 09:57:31: %PIX-4-106023: Deny icmp src outside:64.233.167.104 dst inside:6.6.3.9 (type 0, code 0) by access-group "out_in" Sep 23 03:08:44 pix Sep 23 2005 09:57:32: %PIX-4-106023: Deny icmp src outside:64.233.167.104 dst inside:6.6.3.9 (type 0, code 0) by access-group "out_in"

I can't ping google from 192.168.50.7. I can browse to it (and all other websites) but just can't ping. and no there is no fireall of any kind running on 192.168.50.7 that blocks anything.

:pix501(config)# sh access-list out_in

You have the 'any' and 'interface outside' reversed. The outside interface is never going to generate packets that it tries to send "through" the PIX to "any" on the inside.
