Hello All,
Fisrt Thanks for all the help given, it is greatly appreciated.
I can connect via vpn client to my pix, but I can't ping any internal pc's. I can ping the internal ip of the pix with no problem.
I am testing with 2 vpn clients, safenet softremote, and cisco v4.6. The cisco client connects, and all functions work ping, map drive, rdp etc.
The safenet client connects, but the log files tell me

30505 Not translation group found for tcp source outside 151.197.172.9/1777 dst inside 192.169.2.2/445

that happened when I tried to map a drive.
below is my config, any ideas are greatly appreciated.

WARNING: The following interfaces do not have associated 'route' commands:

The PIX requires a static/default route for any destinations that are not directly
connected to these interfaces, assuming the PIX is not receiving a default RIP

TRY THIS: Configure a static/default route for those interfaces that need to access
non directly connected destinations using the configuration command, 'route if_name

WARNING: NTP servers have been configured but are using no authentication.
TRY THIS: For more secure timestamps, consider enabling ntp authentication with
the 'ntp authenticate' configuration command.

WARNING: You have NTP servers configured that exchange traffic over the least secure
interface, the outside interface.
TRY THIS: Make sure that you want to pass this type of traffic over the outside
interface.

WARNING: There are access-lists defined that are not applied in the configuration

(e.g. used for RADIUS authorization)

WARNING: (VPN) There are 'crypto map' statements in the configuration without a
'nat 0' statement.
Generally, IPsec traffic should be excluded from any NAT operation.
TRY THIS: The 'crypto map {map_name} {seq_no} match address {access_list}' command

by this access list(s) should be excluded from NAT by using the 'nat 0' configuration
command. For example: 'nat (inside) 0 access-list 108'

INFO: The following interfaces have been set to autonegotiate their speed and
duplex settings:
ethernet0
NOTE: Even though the default is to set automatic speed sensing for the interfaces
with the 'interface hardware_id auto' command, Cisco recommends to specify the
speed of the network interfaces; for example, '10baset', '10full', '100basetx',
'100full', '1000basesx', or '1000sxfull'. This lets the PIX Firewall operate in
network environments that may include switches or other devices that do not handle
auto sensing correctly. If speed/duplex are hardcoded on the PIX, configure the
speed/duplex on the neighboring device also.

WARNING: The console is set to never timeout.
TRY THIS: Consider configuring a finite timeout for the console. For example, 'console
timeout 5' will configure a 5 minute timeout for the console.
REFERENCE: For more information, see 'Console timeout' command.

WARNING: There is no banner configured for this device.
TRY THIS: In some jurisdictions, civil and/or criminal prosecution of unauthorized
users is much easier when a banner warning them that their access is unauthorized.
Legal notification requirements are complex and these should be discussed with
your own legal counsel. Once the appropriate login warning has been developed for
your firewall, you may incorporate it into your unit for display before all interactive
logins with the 'banner login' configuration command.

 
Thank you for this information. I'm new to the PIX / cisco equipment.
I was going to begin locking down once I had all the functions I needed working.

Again many thanks for your time & knowledge
 
route inside 10.10.10.0 255.255.255.0 192.169.2.0 1"

What's the next hop for inbound traffic? It's not the network; it should be something like 192.168.2.2

 
Thanks for the reply lgarner,
I am not sure what the "next hop" is.

Could you explain why you think it should be 192.168.2.2?

I thought the route stamnet would direct the vpn trafficc 10.10.01.0 to the internal netwwork 192.169.2.0

Thanks agian
 
Next Hop" refers to the router to which packets should be sent for a certain network when that network is not connected to the sending host (the Pix in your case). In other words, how does the Pix know where to send packets for 10.10.1.0?

Since you have two networks (192.168.2.0 and 10.10.1.0), there must be a router between the Pix and the 10.10.1.0 network:

internet (pppoe)-- pix --192.168.2.0-- router --10.10.1.0

The "router" above will have an address on one interface of 192.168.2.something, and 10.10.1.something on the other interface. I just used "192.168.2.2" as an example since the Pix is using 192.168.2.1.

The 192.168.2.something is the address that the Pix needs to know. When it needs to send a packet to a host on 10.10.1.0 it will send it to the host with the IP address in its route statement. That host will forward it to the next host.

I just noticed also that you're using "192.169", which is not a private network. If that's the actuall address range that you're using, change my examples accordingly.

Also, the vpn client address pool should be on a separate address range. I assumed that you can't connect to 10.10.1.0 addresses, but this might be your problem if VPN clients can't get to 192.169.2.0 addresses.
 
O.K. I see,
however my set up is like this

internet (pppoe)-- (ouside interface)-- pix (inside interface)--192.169.2.1 connects to a switch

I was using the pix as a firewall & router (only one on network)
I thought the 10.10.10.0 addreses were assigned to my vpn client when they connect.
Please correct me wher I am wrong.

Thanks
 
Ahh, there it is. Missed it earlier.

Try this:
nat (0) 192.169.2.0 255.255.255.0 10.10.10.0 255.255.255.0

This will keep the Pix from translating that traffic to the outside address. Ignore my other comments :~/, except do remove the "route inside 10.10.10.0..." statement.
 
Thanks for the idea,
when i insert this command I get this

Result of firewall command: "nat (0) 192.169.2.0 255.255.255.0 10.10.10.0 255.255.255.0"

Well here is where I am.
Quick overview of problem:

1. Using Safenet Softremote, or Cisco v 4.6 client I cannot connect to a VPN endpoint (a DLink 808 HV router)The PIX error log states that

192.169.2.1 Oct 03 2005 16:41:59: %PIX-6-302015: Built outbound UDP connection 750 for outside:151.196.142.42/500 (151.196.142.42/500) to inside:192.169.2.10/500 (141.157.14.15/5)

The log for the safenet client states

The cisco client errors out with
error 412 the remote peer is no longer responding


This problem is strange, because I thought the PIX would let any outbound traffic to the internet. I this senario I am just using the PIX as a router for internet traffic. If I replace the PIX with another router the connection is established with both vpn clients.

My 2nd issue is that when using the PIX as a VPN endpoint I can connect with both clients safenet, and cisco, but the safenet client will not let me ping past the inside interface "192.169.2.1", any other ip addreses in this range do not reply unless I am using the cisco client then all works well.
As I stated earlier I removed the "route 10.10.10.0" statement, and I tried the "nat (0) 192.169.2.0 255.255.255.0 10.10.10.0 255.255.255.0, and I get an error on this

Thank You
 
Try this

nat (inside) 0 192.169.2.0 255.255.255.0 10.10.10.0 255.255.255.0

Please post back the results
