VPN Client setup

[ZenMuster]

Hi everyone,

I'm new to pix501 firewall and VPN setup. I need your help. I would like to connect couple of people at home to our internal network using the cisco VPN client software. At home they have DLS and Cable modems. Where do I start?Do you have a sample configuration? And how do I configure the client Pc as far as networking?

Any help is welcome,

Thank you.


Alex.

Fairly easy to accomplish. instead of re-writing the wheel as they say, here's a good link I found after Googelizing "cisco vpn installation". Many, many more can be found out there.

http://www.mcmaster.ca/cis/network/vpn/ipsec.html

As for a sample config file, firstly I would offer this excellent Cisco resource (only available if your registered) -

http://www.cisco.com/cgi-bin/Suppor...ementation_and_Configuration#Samples_and_Tips

Even easier is to after you run the setup once, take the <connection name>.pcf file (usually under \program files\cisco systems\vpn client\profiles) and modify it as you see fit. Then redistibute the .pcf file with the client and the users are all set.

As for the broadband connections from their homes, the onlyu issues I've run into are applications on the network side that require special ports be open on their side. Everything else works great.

Hope this helps.

Thank you Hofman,

I will try it.

Do I have to do anything on the home PC running DSL besides loading the client?

Alex.

 

[techguru69]

Shouldn't have too change anything, unless they have to access any special ports on your side. one more thing to check on their side is if they are running any personal firewall software - vpn client 4.03D addresses some of the issues with them.

Hi Mike,

I configured the PIX501 firewall. When I try to connect to the netowork from home I get the following error:

Secure VPN Connection terminated locally by the Client.
Reason 412: The remote peer is no longer responding.

At home I have windows XP Pro, DSL modem and firewall disebled.

Below is my PIX config. Can you see what is wrong with this config?

Thank you,

Alex,
The only notable difference I see between yours and mine is the creation of the vpdn groups. Otherwise, I think I more knowledgeable Cisco-guru might have to step in here to help.

Here's my setup for the groups:
vpdn group 1 accept dialin pptp
vpdn group 1 ppp authentication pap
vpdn group 1 ppp authentication chap
vpdn group 1 ppp authentication mschap
vpdn group 1 ppp encryption mppe auto
vpdn group 1 client configuration address local pptppool
vpdn group 1 client configuration dns xxx.xxx.xxx.xxx
vpdn group 1 client configuration wins xxx.xxx.xxx.xxx
vpdn group 1 pptp echo 60
vpdn group 1 client authentication local
vpdn username johndoe password ********
vpdn username janedoe password ********

Sorry if this is no help.

Hello again,

I still get the same error and I cannot connect to the network. Same error as above. I don't even see the light &quot;VPN TUNNEL&quot; on the firewall. So far this configuration is everything, but easy

Could someone take a look at my new configuration and let me know what I'm doing wrong?

thank you,

and thanks Mike I tried.

Alex.
