Can't reach a node/ TTL exceeded

[abarb002]

I'm wondering if you can help me with a problem I'm experiencing. 

I have a Linux box that I can ping other nodes across my network, but cannot ping it from other nodes nor the layer 2 switch it's directly connected too. The only device that can ping this node is the layer 3 switch. I run an an IP scanner and it doesn't pick up this node either. It's like it isn't on the network. Any ide what may be causing this problem? 

Thanks for your time.

Hi,

Does the Linux box have a correct gateway configured?

it looks for me network configuration issue, or check any iptables enabled

1. make sure you have the right gateway

2. iptables -F ( flush FW rules and test)
