L2L between IOS and ASA

I have L2L connection between ASA and Cisco router.

I would like to protect traffic and give full access from PIX LAN to some hosts on the cisco router sites but not inversely.

How to protect the LAN network on PIX site ?

I couldn't find anything on pix site like tcp established in ACL ?

On a cisco routers there I can easily configure some access-list in ipsec-isakmp profile ( set ip access-group in| out )

thanks in advance for any help

Check out the "vpn-filter" command, available in the group-policy.

Re: L2L between IOS and ASA

You cannot control TCP flags - but why would you want to do that in the first place? Note that Pix/ASA is a stateful firewall, not a packet filter.

Re-reading your initial question, I think what you want to achieve can be done using "no sysopt connection permit-vpn" and then permitting/denying traffic in the ACL on the outside interface.

Note however that the outside ACL will apply to all inbound connections over *all* VPN tunnels.
