Hello Everyone,

There’s something I’m missing obviously but I can’t figure it out.

Here’s the thing, I have a Zeroshell VM with 2 Network cards with static IPs as follow.

ETH01: 10.0.2.1/24
ETH02: 10.0.3.1/24

I have two hosts connected to each network card with IPs as follow:

Host1: 10.0.2.10/24 – Gateway: 10.0.2.1/24
Host2: 10.0.3.10/24 – Gateway: 10.0.3.1/24

Now, here’s the weird thing.
Host2 can ping Host1, BUT Host1 can’t ping Host2.

Host1 only reaches ETH02 (that’s 10.0.3.10/24 ).

Host2 is reacheable by any other host in the same network, so it’s not a firewall or OS problem in Host2.

Is there something I’m missing in this configuration?

routing tables (all hosts) and ZS firewall settings probably would help

Firewall: Pings are usually icmp echo-request, echo-reply[/i]

Also, some Windows Firewalls block ping by default. Methinks Win 7 does this. I wouldn’t bet my life on that but I seem to recall seeing some newer Windows OS firewalls blocking pings.
