Configuring a Pix 501

Posted on 2009-04-01
Last Modified: 2012-05-06

I have spent many hours reading and trying to figure this out. I recently picked up a Pix 501 to replace my Linksys BEFVP41 so I could access my works network from home through a vpn with a little more reliable connection.

 I have a PPPoE internet connection. Now after spending all this time working on the proper configurations for the pix. I put in place to see if it would work. I just flat out failed to initilize the PPPoE.

Here is my configuration for the pix. What am i doing wrong? If i have the PPPoE part wrong I think i may have the vpn client part wrong too maybe.

Try running a debug of it.

debug pppoe packet
debug pppoe event
debug pppoe error
debug ppp negotiation

Then reapply the ip addr, and see what the debug gives you
ip address outside pppoe setroute

Ok, for PPPoE use this doc:

vpdn group pppoex request dialout pppoe

!--- Associate the username that the ISP assigns to the VPDN group.

vpdn group pppoex localname cisco

!--- Define authentication protocol.

vpdn group pppoex ppp authentication pap

!--- Create a username and password pair for the PPPoE
!--- connection (which your ISP provides).

vpdn username cisco password *********

Do you have the PDM loaded? If you have web browser access, I'd use the wizard for a VPN client..

Well PDM is installed on the device. Problem is I am having a hard time figuring out which Java Version i need in order to access it. PDM on the device is version 3.0(2)

try Java version 6 release 7, however I am running the new ADSM for version 7, yours might need release 5..

just keep removing each release until you have the working version..

At least on this Workstation, it had them all incrementally installed..

PDM is quite old, and you may experience alot of problems with java.  I suggest you actually disable Sun java in your iExplorer, and just run with the native one - that'll work.

debuggerau: I found it was version 5 release 5

Voltz-dk: what native one? I have disabled all my java plugins and it just kicks back to me saying i need java. Or were you talking about the cli?

I have finally got the PPOE to work. But now there is a new problem. None of my communication from the lan make it to the wan.

I have this nat setupup, but it doesn't seem to work:
global (outside) 1 interface
nat (inside) 1 0 0

No I was talking about PDM, but I suppose it may only apply to iExplorer 6...

That nat & global you have are correct, so unless you have some static or NAT exemption to block it that should work.

If you do run a cli to the PIX, and do debug icmp trace.  Then try to ping from inside to wan (say gateway on wan), what would the debugging show?

Check the ACL's for those LAN hosts.

access-group inside_access_in in interface inside
access-list inside_access_in allow ip any any

This will allow all hosts out..
