Goodmorning,

I have a problem with my Cisco Pix 501.
This device is configured as a Cisco VPN 2 Cisco VPN This is working
perfectly no problems.
I made an alternate configuration to enable pptp to one side of the Office.

The problem is: I can use pptp to the office but then i have no connection
to the other office (vpn tunnel goes down).
I think the problem is this line:

nat (inside) 0 access-list outside_nat0

If i changed the above line to:

nat (inside) 0 access-list outside_nat0_acl --> then works PPTP and i can
access the local network but if the line is:
nat (insdie) 0 access-list outside_nat0 then works the vpn between the two
offices, en i'm unable to access the local lan with my pptp.

Please can someone help me.
Excuses for my bad English i'm Dutch.

Hello Arjan,

I wonder if it makes a difference if you configure the ACL to allow
everything (just for testing):

access-list outside_nat0 permit ip any any

Hi,

I tried this but same problem, the tunnel between the two offices is gone.

The problem is or the tunnel between the two office is up, or the tunnel
between my computer @ home and the office is up.

I don't know what to do, but i must work in a few days.

Can you tell me how i can use pat at the pix 501.

So i can open a port for PCAnywhere or VNC so i can redirect it to a client
at the inside.

Is there anyone who can say how to open poort 5901 i.e. and redirect it to a
host inside i.e. ip: 10.12.14.5 ?

Anyone?

It's all working now.
The problem was to add the following line.

Thanks Georg for the answer.
access-list split permit ip 10.12.14.0 255.255.255.0 192.168.10.0
255.255.255.0
