Hi!

I have been trying to configure VPN-Access on the new Cisco PIX 515E for over 1,5 week now..

The connect, group auth, user auth is going as it should.. I just cant get any traffic trou from the inside to the VPN-Client.

When I try to ping a host on the inside I just send package and get 0 packages in return.

I have looked at documentation at cisco until my eyes starts to bleed..

What am I missing here?

Inside: 192.168.100.0 ,255.255.255.0
Outside: 213.115.x.y ,255.255.255.0
VPN: 192.168.150.0 ,255.255.255.0

My config:

If you have available host addresses left on the 100.0 network, try assigning a subset of that range in your vpnpool1 eg 192.168.100.200 - 192.168.100.250 then change your nonat access-list to
access-list nonat permit ip 192.168.100.0 255.255.255.0 192.168.100.0 255.255.255.0




 
When you ping from the client do a debug ICMP trace from the pix. It shows what the paket is doing when it hits the pix whether it is getting sent to the client, translating or what. This is good in troubleshooting where your packet is getting lost at and will most likely lead you to the cause.
 
Hi agin!

Seem like i solved my problem.. The configuration was correct and working, it was the client end that had trouble..

I tested the VPN-Client at three different sites (with different connections/firewalls) but it seems like all three blocked the IPSEC-Traffic...

No wonder I was going insane with the configuration.. ;)

Thanks for your answers anyway! =)
