So we need to configure two static routes. Therefore, in order for the ASA to reach network LAN2, we need to configure a static route to tell the firewall that network 192.168.2.0/24 can be reached via 192.168.1.1. Rather, there is an internal router with address 192.168.1.1 through which we can reach LAN2. LAN2 is not directly connected to the firewall. Additionally, there is another internal network, namely LAN2, with network 192.168.2.0/24. LAN1 is directly connected to the Inside interface of the firewall. The default gateway towards the ISP is 200.1.1.1. Packet-tracer input Outside tcp 1.1.1.The ASA connects to the internet on the outside and also has a DMZ and Internal zones. How do I pass the RPF-check? I've read many Cisco docs about configuring NAT, but none of them solve my problem here. Result: input-interface: Outside input-status: up input-line-status: up output-interface: Lab output-status: up output-line-status: up Action: drop Drop-reason: (acl-drop) Flow is denied by configured rule Phase: 6 Type: NAT Subtype: rpf-check Result: DROP Config: object network host-10.0.0.2-tcp22 nat (Lab,Outside) static interface service tcp ssh ssh Additional Information: I followed his answer very closely, but the packet-trace test failed on the RPF-check: However, the top-voted answer by Weaver did not solve my issue, so I ask the community again.

I have the exact same problem as described in this question: Cisco ASA 5505 DMZ Setup Issue

There are two ways around this issue:ĬCNA Security Certification Series – #4 Cisco Firewall Technologies – cont’d: The problem is that, by default, ICMP inspection is not enabled on the Cisco ASA so even though the ping from the inside is getting to the dmz, the return traffic is not permitted. However, the task also requires that ping traffic from the ‘Inside User’ to the ‘Web Server’ is successful, so let’s test that:Īs you can see, the ping failed. Two services I found to work are HTTPS and SMTP. I assume it’s some limitation with Packet Tracer. Note: Even though HTTP is also enabled on the Web Server, doesn’t work for some reason. We can confirm this by opening an HTTPS connection from the ‘Inside User’ to the ‘Web Server’: Since the inside interface is on a higher security interface than the dmz, traffic from the inside to the dmz will be allowed by default. Notice the word “ initiate” in that sentence? It means that even though the dmz VLAN cannot initiate traffic to the inside, the inside VLAN can actually initiate traffic to the dmz and the dmz will respond. In that lab, we restricted the dmz VLAN from initiating a connection to the inside VLAN. it will only be able to initiate a connection to only one other VLAN.

In the last lab, we said that due to the license that comes with the Cisco ASA in Packet Tracer (Base License), the 3 rd VLAN we created (dmz) will be a restricted VLAN, i.e. To test this configuration, we will ping the 8.8.8.8 IP address from the Cisco ASA:

However, this short form is not (yet) implemented in Packet Tracer so we must specify it in its full form. This interface name specifies the interface through which the next hop IP address is reachable.įinally, instead of specifying “0.0.0.0 0.0.0.0” like we do on the Cisco IOS, we can shorten it to “0 0” on the Cisco ASA. inside, outside) for any route statement. The route command, used to configure static/default routes on the Cisco ASA, is an example of this.Īnother thing to keep in mind with the Cisco ASA is that you must specify an interface name (e.g. a device on the Internet.Īs I said in the last article, many commands that have “ip” in the Cisco IOS do not have “ip” in the Cisco ASA. The goal of this task is just to simulate an external host, e.g.

Create a local user on the ASA to be used for authentication with the following credentials: Username – “insideuser” and Password – “userpwd”. Enable SSH access to the ASA from any IP address on both the inside and outside interfaces.
