management traffic blocked cause of reverse-path check
i have a problem with "ip verify reverse-path interface inside".
We have a very restricted admin-network, where we have the admin-interfaces of several servers, firewalls and other networkstuff. The perimeter firewall to the outside (asa5580 8.2) has also the management-interface (management-only) in this admin-network. When we than have sometimes traffic from these admin-network via another firewalll through the perimeter firewall, the traffic is blocked cause of reverse-path check.
The perimeter firewall has an interface in the admin-network and is getting those traffic on the inside interface. This traffic is blocked althrough the management-interface is management-only. Of cause i could make the perimeter firewall the admin-network firewall, but i don't like that, because our admin-network is special secured and a separate physikal infrastructure.
Is there a possibility to selectivly disable the reverse check for the admin-network or to ignore the hole managment-interface for all the routing stuff?
Re: management traffic blocked cause of reverse-path check
If traffic enters the outside interface from an address that is known to the routing table, but is associated with the inside interface, then the security appliance drops the packet. Similarly, if traffic enters the inside interface from an unknown source address, the security appliance drops the packet because the matching route (the default route) indicates the outside interface.
You can disable RPF on specfic interface if you like. Also you can route all management traffic via the management interface on the ASA if you like.
