Hi,

I am using IPSec on IPCop to route traffic to a remote network behind a
Cisco ASA.  It is working but there are a couple of issue I am having with
the finer details of routing/firewall configuration.

Issue 1:

I need to route to multiple remote subnets but the UI doesn't appear to
allow this?


Issue 2:

Applying firewall rules to the inbound traffic from the IPSec tunnel
doesn't appear to work the same as other interfaces.  I would expect to add
route to DROP all traffic from the remote subnet destined for the GREEN
network.  If I do this then traffic stops in both directions because the
rule isn't constrained to NEW TCP sessions.

I therefore have to add another rule for every service I expect to use on
the remote network and ALLOW traffic from the source port.

Is this expected?




Best,
James
