Can't Ping Across PIX 515e

I am able to connect to my PIX 515e but after I am connected I can't ping across it. I try to ping the inside from a PC that I have directly connected to the outside. Here is the config file, hope this helps.

Re: Can't Ping Across PIX 515e


For outside to inside connection you need a couple of things - static and ACL.

Here's a sample configuration that would give you an idea.

Let's say you have the following setup. If you want to ping the inside host from outside then the configuration below would make it work.

Inside PC -

Outside PC -

static (inside,outside)

access-list acl_outside permit icmp host host

access-group acl_outside in interface outside

In this example the static is doing no-nat of inside address but you can use a global address for the inside host if you desire so.

It seems to me that you are creating an explicit ACL to allow the outside PC access through to the inside. What I want is any PC that gets a new IP address from the vpnpool to be able to ping the inside.

Is your way the only way to do this, because it seems to bypass the vpn.

After you connect the VPN Client and try to ping an IP Address on the inside, do you see counters increasing under Packets TX and RX on the client side. If you see only TX getting increased, can you do a "show crypto ipsec sa" and look for packets Encrypts and Decrypts.

Also, do a clear xlate on the Pix and try pinging again.

I hope it helps.

crypto map mymap 10 set reverse-route to allow your routing to work correctly for this tunnel back to your client. And if you want to access the internet given you do not want split tunnel and you have DNS servers specified under your group accross this VPN tunnel you should specify your config like this.

nat (outside) 1

global (outside) 1 int
