    Hello all,

    I configured two VPN, one between two PIX 501 (6.3(1)) and one between a PIX
    and a Cisco VPN Client 4.0.3 (C).

    Well, the VPN between PIX works fine, while the VPN between the Cisco VPN
    Client and the PIX doesn't works. The PIX assigns the IP address (in the
    pool) to my remote PC but I cannot ping the internal interface of the PIX

    Thank you in advance for the answer.

    More help...
    I removed the VPN site-to-site configuration and the VPN between Cisco VPN
    Client and PIX works fine, together they don't work.
    Thank a lot in advance.

    I have the same problem.

    I have an IPSec tunnel between my PIX 515E and a remote office via their ISP's VPN concentrator. this this tunnel up, my cisco VPN clients can connect but NOT pass traffic.

    I have the following related access-list entries (101 is for my VPNGroup using cisco VPN client. DalVPN is for my IPSec tunnel between our PIX 515E and the VPN concentrator):

    access-list 101 permit ip
    access-list DalVPN permit ip

    IF I use:

    nat (inside) 0 access-list 101

    THEN my Cisco VPN clients work great, but my IPSEC tunnel to Dallas dies.

    IF I use:

    nat (inside) 0 access-list DalVPN

    THEN my IPSec tunnel to Dallas works great, but Cisco VPN clients can not pass traffic.

    What are we missing... this is very frustrating. Any ideas anyone?

    My solution

    I have solved the problem:

    Added the following to my 101 access-list to except traffic from the NAT process:

    access-list 101 permit ip

    Poof! now both the PIX to Concentrator IPSec tunnel and the Cisco VPN Clients pass data back and forth properly.
