Juniper SSG20 VPN

I've established a VPN connection with the Juniper SSG20 FW but once inside I am unable to ping any of the devices on the LAN.

I heard about Shrew. I had customers that used it in the past. Keep in mind you get what you pay for 8) Well good luck with your "open source" project. BTW "open source" doesn't mean "free source". I think people are a bit confused about the term "open source". Also I didn't think Windows 7 was "open source" or free for that matter. So I guess that sort of shows a certain contradiction of your talk.
Just ask Larry Ellison about "open source" and his takeover of Sun and Solaris hehe.
Are there any firewall rules that are blocking ping; anything showing up in the logs?  Does the Ip address you are handed have a route to the inside network and vise versa?

Can you browse file shares?

Ping depends on icmp, try telnet to a port

The ip address im given is from the pool, how do i set up the route to the inside network an d be able to ping other devices.
Things to observe:

1. Ensure that no other IPsec VPN client is installed on the client computer. Remove ALL such clients.

2. Temporarily disable Internet Security software components (Stop and Disable the Security Software services and reboot with the services disabled to validate whether they cause interference or not).

3. Verify that none of the Windows native IKE and IPsec Services are running. If they are Stop and Disable them (Computer Management - Services - IKE and IPsec Services)

Disabled all the services and ensured no other IPSec VPN client was installed though I am still unable to connect to any device on the network.
What OS are you on?
What IPsec VPN client are you using?
How do you assign the IP adddress to the client? Ikeconfig mode?

Im On ScreenOS 6.0 with the Windows 7 VPN client and the addresses are assigned via an ippool on the Firewall as I configured it L2TP w/o IPSec Juniper Configuration Guide,
OOps that's your problem. You DO NOT use the Windows 7 VPN client. It's not a standards based IPsec vpn client. Please use a standards based proper IPsec VPN client. Problem resolved.

Which Free VPN Client do you recommend I use.
What you mean "Free"? Why does it need to be Free?? What is more important to you. That it works or that it's Free?
Go and do yourself a favor and get the NCP Juniper client You do have a job do you or do you work for Free?

Okay Smart guy, This is a project which utilizes open source as to keep expenses at a minimum but looking around I've found which provides the free software but tks anyway.
