VPN connection

j.rounkles · ‎07-19-2005

At home I have a Pix 501. At work we use a VPN 3000. Everyone else can connect and work from home except the users who have a Pix (such as myself). The VPN client connects (or atleasts says it does) however I cannot use any terminal service (ie Remote Desktop Connection). We use this on several servers at work. I obtain all the Network settings from our DHCP server at work (IP, Gateway, DNS, etc.). What am I missing in the Pix that is keeping my from browsing the network? TIA for any help.

When you connect into your network from home are you using a PC with a VPN client or are you using a pix to concentrator VPN?

j.rounkles · ‎07-20-2005

Using the Cisco VPN Client (ver. 4.6.03.0021).

what is your config?

I have the following config and remote desktop works fine:

-Internet-827(NAT overload)-PIX(NAT0)-PC(vpn client)

Here is a copy of my config...if you see something I should have that is missing please advise...

I apologize for my ignorance but please be specific on what I am missing and what I should add.

try this command:

isakmp nat-traversal

added lines and still not able to connect through RDP connection. (Trying to connect using IP address and not machine name.)

quick question on your config. what is the ipsec config for? Are you using it to connect to another vpn device or is it to allow vpn into your home network?

try the following:

disable the ipsec stuff on the pix.

set your vpn client to connect using ipsec over tcp

port is usually 10000. check that the office vpn

concentrator is configured to support ipsec over tcp

port 10000

Still no go...it doesn't seem that I am decrypting any packets on my end at home nor am I establishing any routes...see attachment screen capture

johnd2310 · ‎07-25-2005

try capture command on the pix to see what traffic is going through.

used any prsonal firewall on the pc?

is there any device between pix and internet? have you tried connecting pc directly, bypassing pix?

I have the Win XP firewall disabled, Internet comes through my wireless antenna which has Pix's MAC address tied to it. If I want to test by going around Pix then I have to call ISP and have them enter another MAC address. All other users that are not using a Cisco PIX are able to access the Terminal Servers via VPN connection. We are all using the same VPN Client version.

having a look at the posted config.

the crypto map is matching acl 101, but acl 101 is missing. would you plesse re-post the config?
