Hi to all,
I am trying to configure our PIX501 to allow us to use Cisco VPN Client software to connect to other PIX501 through local 501 and internet. I am doing something wrong because I can connect to the remote PIX501 but cannot see anything on the remote network (connecting to the remote LAN without local PIX501 shows no such problems). Local PIX shows warning messages in LOG: "305006:portmap translation creation failed for protocol 50 src inside:LOCAL_PC_IP dst outside:DESTINATION_PIX_IP" Connecting to our VPN from outside works OK and surfing inet from our side is also troublefree. We are connected like this: ISP->xDSL router->PIX501->LAN. The xDSL router has no restrictions set, it just forwards everything to PIX.

What is wrong with config of our local PIX501?
Thanks in advance for any help or comments.

You nees to make sure this command is in your remote pix that you are connecting to : isakmp nat-traversal 20 like in your local pix.

Also check that when you are connected the vpn stats say something like transparent tunneling enabled
