PIX, server, ping problem...

[homeboarder8]

Okay I thought I had this problem solved but it seems I have a different problem all together. So here is my situation... I have two servers behind a PIX 501. The PIX has a static external IP, and both servers have their own static external IPs that are being forwarded through the PIX to local IPs. I can ping the PIX from an outside network, but I cannot ping either of the servers external IPs.

Any help will be appriciated here.

Thanks!

Make sure software firewalls installed on server permit ICMP (Like windows firewall) try temporarily disabling then ping

jfbeam, ip does not include icmp.

Okay here is where I stand. I can now ping out from the server, but still I cannot ping the external IP addresses of either of the servers. Note that I am using a static route for the external IPs to the internal ones (Not sure if that makes any difference). But here is the updated running config:

Thanks again for all the help.

You have to allow the ping reply in your outbound acl since ip does NOT include icmp.

access-list outbound permit icmp any any

[homeboarder8]

Okay I entered that access-list in but I still cannot ping the external IP addresses...

[husycisco]

If following commands do not work, I recommend you to upgrade your IOS to 6.3(5)

no conduit permit icmp any any

conduit permit icmp host 77.xx.xx.55 any

conduit permit icmp host 77.xx.xx.54 any

icmp permit any outside

one last possibility if above does not work

no floodguard enable

again double-check if ICMP is enabled in any software firewall (make sure it is not allowed to a specific range of IPs, like windows firewall options)

[homeboarder8]

I entered your settings, and still it does not work. Could you point me in the right direction to upgrade to firmware?

Thanks.

[homeboarder8]

I entered your settings and I am still not able to ping the servers. Can you point me in the right direction as to where I can download the updated firmware? And I am still open to other ideas....

Thanks for the help!

[husycisco]

You can download 6.3(5) from following link

http://www.cisco.com/pcgi-bin/tablebuild.pl?topic=268439592

But you need a CCO account

[homeboarder8]

I upgraded the firmware but the problem still exists. Could this have something to do with the static routes? And if I set my servers to the external IPs could I still use PPTP for secure remote connections?

Thanks!
