Decrypted VPN traffic and access lists on outside interface of PIX

Hello All,

Can someone please clear something up for me.

Is decrypted traffic from a site-to-site VPN sent back through an access list that is applied to the outside interface of a PIX?

For example:

If a crypto map match entry uses an access list that includes:

permit ip 192.168.10.1 255.255.255.255 192.168.20.2 255.255.255.255

Assuming that the VPN successfully connects and there is full IP connectivity between local host 192.168.10.1 and remote host 192.168.20.2.

If I then use the access-group command on the outside interface and apply an access list that includes:

permit tcp host 192.168.2.20  host 192.168.1.10  eq telnet
deny ip host 192.168.2.20 host 192.168.1.10

Would access be restricted to only telnet traffic from remote host 192.168.2.20 to local host 192.168.1.10

Thanks.

John
