vpn over fw

Carlos A. Silva · ‎03-19-2003

i have the following setup:

pcwithvpnclient----(in1)---pix1---(out1)---internet---(ou21)---pix2---(in2)

say i establish a vpn between the client and pix2.

once that that vpn is established, will that make the pc with the vpn client vulnerable to the user on in2? that is, i understand that i will be able to make requests to the hosts on in2, but will those host be able to do stuff to the pcvpnclient?

Hi,

it depends on your access-rules on pix 2. If the VPN-tunnnel is established then all traffic matching the crypto config is forwarded to the tunnel endpoint. Stateful inspection (conn-table, xlate, fixup, etc) is working of course. So define access-rules that allow exactly what your client needs and reject all unwanted traffic.

Hope this helps

so what you're saying is i should create access lists to deny specific traffic over the established vpn to this pc? what i was worried about is that i know i will be able to reach the in2 on pix2 no problem, but i don't want anything on in2 to be able to do stuff to my pc on in1.

thanks,
