Setup Remote VPN on PIX 501

I'm trying to configure a remote VPN where clients can connect using the VPN client and have access to the internal network. I'm new to the PIX, and seem to be having some trouble.

All configuration is done through the PDM.

I used the Wizard to create the vpn server.

Internal Network 192.168.1.0/24 VPN IP Pool 10.10.10.1 - 10.10.10.11

And for the exemtion I just clicked finish, so they will have access to the internal network.

The client can authenticate with the VPN server, and be assigned an ip address, however cannot ping or access any internal clients, nor ping the 192.168.1.1 internal interface on the PIX. Where am I going wrong?

Detailed step by step would be great.

Thanks!

Tom

The text version of your configuration (with passwords scrubbed) would help.

I am not going to try to guess what the PDM might or might not have done on your behalf -- too many different screens and you would have to describe each configuration step and each drop-box selection and so on for me to be able to replicate what you ended up with. The text configuration is *much* easier to answer questions about.

My -guess- is that the PDM didn't happen to turn on sysopt connection permit-ipsec but I don't have enough information to be sure.

For your purposes you should assume that the VPN clients will never be able to ping the PIX inside interface IP. [If you *really* needed them to be able to do that, it would be possible to configure, but it's a relatively advanced configuration and seldom worth the bother.]

I've also tried to ping internal machines, no go. Client side I get this error:

In order for the return traffic to reach the VPN clients from your inside hosts, your vpngroup IP pool needs to be in a different subnet than your inside address. For example you could use

ip local pool donkpool 192.168.2.50-192.168.2.60 mask 255.255.255.0

as long as you made the appropriate adjustments to other parts of the configuration.

Just for clarity: what I said about ip local pool does NOT apply to the dhcpd addresses. Hosts that are "inside" the PIX need to have addresses that are "inside" the PIX, but hosts that are "outside" the PIX (e.g., the VPN clients) need to have addresses that are "outside" the PIX.

I've tried with another IP Pool for the vpn clients (10.10.10.1-10.10.10.11) with the same problem. The exact same error on the client (tried from multiple machines, even toggling modes)

Please quote context. There's only one regular poster in these groups who uses googlegroups as a regular email reader; the rest of us do not have the context "right there" to look at.

I'd like to see the editted configuration.

This is my current config, which is still receiving the route error:

Walter,

Are you refering to me here?

I do consider myself a regular contributor however I have no idea if that may be the viewpoint of someone else?

I use Google groups for all my Usenet access and I do try to contribute as much as I can. From my Google View I suspect that it is difficult to appreciate the tools used by other users of this group and I am concerned that I do not meet their requirements.

I have recently been making an effort to appropriately 'quote' past messages even though I have to do it entirely manually and from my 'Google' view it appears superfluous.

Anyway, please let me know if I am causing difficulties and inform me of possible improvements to my posting style. My goal is to communicate as effectively as I can.

More contentiously:- Why don't you use Google Groups too?!!!!!!:-) Seems a perfect plan to me:-)))))))))

BTW Google Groups is not a 'a regular email reader'.

Thanks,

Me.
