Hi I have a site to site VPN on an ASA device running OS 8.4
my side of the network is on 192.168.1.0 / 24
the other side of the VPN is 10.0.0.0 / 24
I need to set up a rule so that while I can access all hosts on 10.0.0.0 / 24
none of the hosts on 192.168.1.0 / 24 should be able to access our side of the tunnel.

Is this possible?

I think that should be possible. If you have something like sysopt permit-vpn in your config, remove that. After that you need to allow vpn traffic through an ACE on the outside interface just like any other traffic from the outside.
So if you don't add a rule I think it would work like any other traffic through the ASA. From the inside to the outside and return traffic should work.

Ok,

Could you tell what you did? And could you have a look at the logging to see if anything shows there?

 The vpn-filter is applied to post-decrypted traffic after it exits a tunnel and pre-encrypted traffic before it enters a tunnel.
Exercise caution when you construct the ACLs for use with the vpn-filter feature. The ACLs are constructed with the post-decrypted traffic (inbound VPN traffic) in mind. However, they are also applied to the traffic originated in the opposite direction.
