PIX VPN Firewall-Rules
Posted by Michael Kiessling on December 18th, 2003


Hi,

I want to restrict the access from a vpn tunnel inside my LAN.
Where do I have to set the access-list?
On the outside interface, on the inside interface (I don't think
this works), or do I have set the rules at the access-list which
desrcibes the tunnel (encryption domain)?

I don't have the possibilitie to set up a test environment - so maybe
someone did this before.

Thanky ou,
Michael

If you disable sysopt connection permit-ipsec, then the access-list
applied to the interface the tunnel terminated on will filter traffic
that arrives from the tunnel.

If you leave the sysopt in place, you can filter traffic on the internal
interface(s) to prevent traffic from entering the pix before it hits the
tunnel.

The second option is effective if you have control of both sides, as it
does not filter traffic from the other peer, but rather filters what you
send to them.
