Cisco CP Express out Ping

Hello,

I am having some issues with pinging my ip address from an outside computer.  We are using a Cisco CP Express Router with no Firewall currently configure.  We have it setup with a wireless signal for in house users. Is there a command that I can type to figure out how to change this? Or is there something on the GUI that allows me to change it so outside computers can ping my address?

Thanks

Can you post the config from the router (without passwords, etc)?

interface GigabitEthernet0
description $FW_OUTSIDE$$ES_WAN$
ip address 555.555.555.555 255.255.255.252
ip nat outside
ip virtual-reassembly
zone-member security out-zone
duplex auto
speed auto


Remove the zone-member security out-zone command from the interface and try again.

Craig,

Will this remove all the security on that?  If that is the case we do not want to do that.  All we want is outside the networks computers to be able to ping the address to one of our servers.

It will, but the purpose of removing that command is purely to see if the firewall is actually blocking pings - which I think it is.

You need to allow pings to the IP address of the GigabitEthernet0 interface.  You won't be able to ping the server's IP address behind NAT as it's not a routable address.

Craig,

This is something that we do not wanna do since it opens us up.  All we want to do is ping our external ip address.  Is there another way we can test this?
