I'm trying to establish a Quick VPN connection to  Linksys 4400N VPN router from a computer behind a Cisco Pix 501.  The ports that need to be allowed on the Pix are 443 and 60443.  Also ping needs to be allows through the Pix.  Linksys logs show a connection is establish but the connection fails with error "Failed to ping the remote VPN router - Ping was blocked, which can cause an unexpected disconnect."  I also have another error on the Linksys router that says the Pix did not respond.
Attached is my config file.
Thanks for any help!

For opening ports to an IP, you should use 255.255.255.255 as the netmask.
You seem to have an error for the 3389 and the 6905 ports:
static (inside,outside) tcp interface 3389 192.168.10.2 3389 netmask 255.255.255.255 0 0
static (inside,outside) tcp interface 6905 192.168.10.2 6905 netmask 255.255.255.255 0 0

Currently you are only permitting ping/icmp reply from an external host.
I.e. if you ping from the pix to 72.105.60.62, I think you'll get a response.

Another option is to disable the ping check on the linksys VPN configuration.  Assume the host is up.

Thanks for the info,
I can connect in through port 3389 with no problem when using RDP.  
Can I open the 443 and 60443 ports for use by all clients behind the Pix or do I need to have a command that routes this traffic to a specific internel IP?
I beleive the Pix needs to accept a ping request from the Linksys and respond to it.

Thanks for the input!

Usually clients behind the PIX can access anything outside unless you have setup access lists to limit that.

You do not have any access list that prevents LAN systems from accessing any resources on the internet.

I do not see any VPN configuration on your PIX. So when the linksys attempts to establish a VPN, it gets no response back.
you would likely need to add to the pix configuration a
nat (inside) 0 to allow VPN Ips from the remote location to get to your LAN side and vice versa.
You should look at the cisco site www.cisco.com for VPN on PIX.  They have many examples there.
