Currently I have a small inquiry about a PIX506E, this device is configured and working fine, VPN is also configured on it to allow LAN-to-LAN connection using crypotomap and user authentication access PPTP with MSCHAP.


Problem Description

- I connect to the device using windows VPN S/W, I get authenticated and connected.

- When use the "ipconfig" command from command prompt, it reveals the internal IP assigned to the PC by the firewall.

- I can not access or ping any PC in the same subnet ID, knowing that if connect to the inside interface of the PIX, you can ping it and access the PDM (which means that ICMP is enabled)

Dear Guys,

Let me add this to make it more clear as the points bellow:


- I am testing a PIX 506E, connected to a switch to the outside Interface with IP 190.200.150.48 and a PC1 with IP 190.200.150.49 connected to same switch

- The inside interface address of the PIX is 192.168.10.200 and a PC2 is connected to the inside interface with IP address 192.168.10.200

- Ping form PC1 to out side interface, OK

- Ping from PC2 on the inside interface, OK

- from PC1, establish a user VPN connection to the firewall ( where the PIX will assign another IP address from already specified pool )

- now the ipconfig of PC1 is:

190.200.150.49

255.255.255.240

190.200.150. 48

PPTP address

192.168.10.200

255.255.255.255

192.168.10.200

- No what I need is, as long as I am connected through the VPN, I need to reach the inside PC2. how can I do this
