PIX 515E VPN setup issue-unable to get to inside network
I have a PIX 515E with failover until up and running as a firewall with no problems.
I have been attempting to setup a client VPN with split tunnels using local auth.
I am setting this up via the VPN Wizard in the PDM.
I am not afraid of the CLI, but I have never done this before and figured it was worth a shot....
Also, I did look at the Cisco config examples, but I have been staring at this for so long I am unable to figure out what I need to change.
Currently, I am unable to ping any of the servers on the internal network but I am able to log on to the VPN with local auth.
Super urgent so I am setting this at 500.
Current config follows- firewall rules and passwords removed for your viewing pleasure. Real IP's changed to x.x.x.0.

1- No, the primary LAN that will be accessing this is 10.x.x.x
We may have other remote users that are accessing this via 192.168.1.x LANS, but I won't worry about them right now.
2-Yes, 192.168.1.4 is the default gateway for all machines behind the firewall.

never seen this before.
is split tunnel scratchy_splitTunnelAcl same as ELM_splitTunnelAcl ? Why is it permit any any? This will force all traffic thru the tunnel and defeats the purpose of the split.
if you connect the vpn client, look at the statistics on the client (or on the server with a sh crypto ipsec sa) to see which way the packets are encrypted and decrypted. It should tell you which way the packets are going thru the tunnel. If none are encrypted or decrypted, nothing goes in the tunnel. If it goes one way, we'll have a clue as to what the problem is. Could you post the stats?

Yes, scratchy_splitTunnelAcl is te same as ELM_splitTunnelAcl.
Sorry, my fault.
I don't know why it is permit any, this config was done entirely through the VPN Wizard.
The wizard has lost it's power!!!!
I tried adding isakmp nat-traversal 20, it didn't work.
Stats from the client indicate that packets are being encrypted, but not decrypted. I also have a bunch of packets discarded.
Many sent, but none received.

Only thing I can think of is the ACL -
access-list outside_cryptomap_dyn_20 permit ip any 192.168.10.0 255.255.255.0
Can you change it to:
access-list outside_cryptomap_dyn_20 permit ip 192.168.1.0 255.255.255.0 192.168.10.0 255.255.255.0
(or 192.168.0.0 255.255.0.0 depending on how big your range is internally.)
Never used an "any" in a cryptomap ACL before...

Tunnel is up. Client is encapsulating but we are not recognizing packets inbound to decapsulate them. Hmm.
ASKER
Changed the line. Still the same thing. No packets are being decrypted.
Pull these commands:
vpnclient server 192.168.1.4
vpnclient mode network-extension-mode
vpnclient vpngroup scratchy password ********
These are for easyvpn remote. The 515 Doesn't even support EasyVPN Remote, and you aren't using it anyway.

Nope. Still not decrypting packets.

Cool. Now I can access all of the servers ion the inside network!!!!
Adding the isakmp nat-traversal 20 line to both my routers did the trick.
Unfortunately, split tunneling isn't working, I can ONLY access the servers on the internal network.
I also can't ping the internal interface (not that this is a requirement).
What do I need to do to get a split tunnel?

What version PDM? 3.02?
Did you lose the nat-traversal line?
While connected, open the VPN client, Statistics, and check the Route Details tab. You should only see 192.168.1.0 in the Secured Routes
Try "clear xlate" and try it again
If that doesn't work, let's try reversing the nat0 acl again:
access-list inside_outbound_nat0_acl permit ip any 192.168.10.0 255.255.255.0
no access-list inside_outbound_nat0_acl permit ip 192.168.1.0 255.255.255.0 192.168.10.0 255.255.255.0

PDM needs pdm commands for everything you have in the config - add a PDM location 192.168.10.0 outside.

Tried clear xlate.
Reversed the line.
Still not able to get to the internal network but able to use the split pipe (my internet connection) when connected.
