VPN setup
Hi all,
after setting up vpn through PDM, which i dislike the more i use it, i find myself been able to log in through a vpn client, and not been able to do much. When i log in i cannot browse the inside lan, i cannot connect to the internet which i am not sure why as i thought only traffic going to lan would travel through tunnel, all other trafic go over net from where i made the vpn connection. I can also ping my outside firewall and get a echo reply which i dont want. I am pretty sure it has to do with the routes--split tunnels ??? to why all trafic is going over tunnel, b to do with access-list to why i cannot browse in lan, why outside returns a echo i have no idea. be grateful for any help, below is config. Also the PDM put a load of stuff in there which I am not so sure about, not sure if it is all needed crypto 20, 40, do i need both ???

Hi Irmoore,
Ah Microsoft PPTP and a lovely server/client GUI 10 minutes to set and open two ports and VPN I can. But I cant like it that much if i am here trying it with a PIX :-)
Ok I have done as you said above, it makes a connection to the server ( so group name/password working (VPN is Working) But when i try to authenticate user/password it kills connection. When I look in the cisco client 4.6.01.009(microsoft never had so many revision (bit like dont touch a running client :) ) log it reports "inbound connections not allowed" below is new conf. Also I can still ping PIX from outside this scares me more as i thought the pix was fairly locked down.
Thx

Great Work, Irmoore.
Now I really need to take time out and learn more about networking and PIX, and read a manual or two.
Thx again :-)

Glad to help!
LOL! It's a "work in progress" at best...
I'm assuming you mean with the Cisco VPN client, not the Microsoft PPTP VPN client.....
>.When i log in i cannot browse the inside lan,
Let's fix this one by using a totally separate IP subnet for the Cisco VPN clients and clean up some of the other stuff.

>i cannot connect to the internet which i am not sure why as i thought only traffic going to lan would travel through tunnel, all other trafic go over net from where i made the vpn connection.
ALL traffic goes through the tunnel by default unless and until you add split-tunneling for the local lan only (this part is easy with the GUI)
Add split-tunneling:
access-list split_tunnel_acl permit ip 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.240
vpngroup Walsh split-tunnel split_tunnel_acl
Done!
Happy VPN'ing!
