Outbound ACL with sysopt Permit-VPN Enabled

Hello,

I have an interesting question.  Is it possible to have sysopt permit-vpn enabled and still be able to have an outbound ACL on an inside interface that would match and drop the traffic?  I cannot use VPN filters as routes are learned dynamically and are split unevenly across multiple inside networks.  Disabling syspot permit-vpn is not an option that I would like to entertain.

For example, I would like a certain ip pool to be able to access networks learned on inside-network-1 but denied on inside-network-2, inside-network-3, inside-network4.  Another pool would be allowed to inside-network-2 and denied on inside-network1,3,4.

 

Can a VPN-Filter Deny an outbound interface?

Hi Kelyrossd,

 

You would that with split tunnel, example of partial configuration:

 

ip local pool VPN-POOL-1 192.168.10.1-192.168.10.62

access-list FILTER-VPN-TRAFFIC extended permit ip host 192.168.0.1 192.168.10.0 255.255.255.192

group-policy EXAMPLE attributes
 split-tunnel-policy tunnelspecified
 split-tunnel-network-list value FILTER-VPN-TRAFFIC

 

Regards,

Aref

Unfortunately, as previously stated the routes are learned dynamically (several thousand).  I will also add that all traffic is tunneled.
