PIX 501 simple setup

cworsham80 — Fri, 21 Feb 2020 11:08:45 GMT

I am trying to setup my PIX 501e and i am having trouble. i'm trying to set it up as simple as possible. authentication to be done local on the PIX, just one user is fine. no AAA server. once in, i want to permit all ports for all traffic. i think i have it setup but i cant seem to log into it, is there anyone that can help me? I can post my show command if helpful.

Hi,

Can you post the configuration along with information on how you are trying to log in. That is through telnet, SSH, console, VPN, etc.

Regards,

Arul

I currently have two ASA 5505's in place and to VPN into those i have been using the cisco VPN client 5.0.00.0340. I would love to be able to use this same client to log into my PIX network as well but not manditory, i can get the vpn client to connect to my PIX, it authenticates on the group level, prompts for user info, but just remains at contacting security gateway until it times out. I have been programming (or call myself programming) the PIX using the PDM with an old win 2000 box. hope this is what you were looking for. Any and all help is greatly appreciated

Hi,

vpngroup demo address-pool VPN_POOL

vpngroup demo idle-time 1800

vpngroup demo password ********

If you are using the above vpngroup, that is Group - demo and password - ***** and VPN Client 5.0, then you should not be prompted for a username/password since there is no user authentication configured.

Can you enable "isakmp identity address" on the Pix and try connecting using the VPN Client 5.0.

If you still having issues, can you post the outputs of "deb cry is" and "deb cry ips" from the pix and logs from the VPN Client.

Regards,

Arul

I appreciate your willingness to work with me on this, just not getting very far. i put in the three commands you requested into the PIX and the only feedback that i got was "this command has been sent to the firewall" for each of the entries. I am also pasting what i have in the logs window of my client, which i'm afraid isn't much. its just not making good sense to me. am i making this harder than it has to be? I would like to be able to use the client with the group authentication, user and password both "demo" no further prompts would be nice.

Hi,

Can you remove the below command:

crypto map outside_map client authentication VPN

and configure this one and test the connection again.

crypto map outside_map client authentication LOCAL

that helped a lot, it will now let me connect from my pc behind the ASA out to the internet then into the PIX i get authenticated there and get the local ip address of 192.168.0.130 which is the beginning of my ip pool. so far so good. behind the pix i have a machine sitting at 192.168.0.15. I cannot ping from my .130 address to the .15 address. how can i open up the doors so that i am seen as being local to the .15 box?

Re: PIX 501 simple setup

ajagadee — Wed, 03 Dec 2008 21:14:24 GMT

Hi,

Thanks for the update and rating.

I dont see anything obvious that will block traffic between the VPN Client and the subnet behind the Pix.

Is the 192.168.0.15 a valid host on the network. Can you ping this ip address from the Pix itself. Also, what is the default gateway of this host. And, can you try pinging a different ip address via the vpn client and see if it works. Maybe 192.168.0.40 address, the first one in your DHCP Pool.

Also, if everything looks good, try doing a "clear xlate" and then try the connectivity again through the tunnel.

Regards,

Arul

the machine behind the pix (formerly .15) i have now made DHCP and it was assigned 192.168.0.40 from the PIX. my outside connection coming in is still 192.168.0.130. from the 192.168.0.130, once connected I can ping the outside address of the pix (206.248.243.98) but cannot ping the inside address (192.168.0.1) nor can i ping the machine behind the pix (192.168.0.40)

from the .40 machine, i can ping 192.168.0.1 (inside of pix) but not outside or the .130 address.

from the pix ping command, i can ping 192.168.0.40 but not 192.168.0.130, even though i can go into the monitor feature of the PDM and see there is one tunnel in place.

am i running into something stupid because the machine that is getting a vpn address of 192.168.0.130 has a local address behind the ASA of 192.168.0.52. All subnets for all 192 addresses are using 255.255.255.0
