Dear friends, I have an ASA 5510, but cannot ping from DMZ to Outside1 Networks (I am trying to ping 172.1.1.x, that is located on a cisco 892 router connected to interface Outside1). cannot ping viceversa too. I have the same scenario from Inside to Outside1 but it works fine
Does someone can help me?
Here's my config

Hi, the security level of DMZ is lower than your Outside1, this is why you will need to specify ACL to allow icmp from that specific host or you can also use icmp command.
The reason you are able to to ping from Inside to Outside1 is because their security level is the same and you have that same security command configured.
04-16-2014 06:15 AM
Dea Rudy, I am alittle bit newbie on this. Can yo help me designing an ACL for any kind of traffic from DMZ to Outside1 and viceversa please.
04-22-2014 09:14 AM
Dear Rudy, I was inspecting my configuration and I see the following curious behavior. I have 2 interfaces 100 security level (Inside and Outside1), also 1 Interface with 0 Security level (Outside) and 1 with 10 Security Level (DMZ). I have fluent traffic between DMZ and Inside bi-directionally but don't have any traffic between DMZ and Outside1. Why? what's missing in the configuration.
