Cisco VPN v5.0.07.0290

Dear All,

I am able to login to my client's network via cisco vpn, but my outbound connection is not encrypted, how can I resolve it?

When I do a tracert, I see my own internal devices IP address for the first two hops and then the request time out.

The actual connection should be outside my router.

over a maximum of 30 hops:

  1     1 ms     1 ms    <1 ms
  2     2 ms     1 ms     4 ms
  3     *        *        *     Request timed out.
  4     *        *        *     Request timed out.
  5     *        *        *     Request timed out.

That would not imply it is not encrypted, to me it looks like it is not tunneling all traffic, split tunnel so you can access the Internet locally and internal over VPN.

Although I can connect, but I am unable to ping my client's dvrs.

I even tried to ping their IP address but I get no replies.

Successful connection and no traffic passing is nearly always NAT related :)

Pinging over Von is tricky, NAT is probably the problem. In most initial setups ping and trace route will fail or in trace route case be incomplete.

The NAT is an issue at my firewall's end or at the destination to whom I am trying to connect to?

Anyway to find out if the NAT is not working in either ends?

>>Anyway to find out if the NAT is not working in either ends?

Yes, issue a 'management-access inside' on both ends then ping the inside of the firewall at the other end of the tunnel, if that replies and nothing else does then it 99.999% a NAT problem

Hi! Pete,

I am sorry as my knowledge on cisco is not very good, how do I issue a 'management-access' ?

Dear Experts,

I finally found the reason.

I have two connections in my Cisco VPN.

One of them under "Transport" had IPsec/UDP

The connection in question which I am having issues with, only have IPsec.

So in order to resolve it, I have to:

1. Right click on the connection.
2. Select Modify
3. Click on the Transport tab
4. Put a tick against Enable Transparent Tunneling
5. Click Save

Voila, I can VPN without any issues.
