ping

Today I am working on this issue and I would love your ideas.

There is a network with something like this

LAN 1 -- WAN CHANNEL--- LAN 2

The LAN 1 have two segments.

When I make a ping from LAN 1 segment 1 it works like a charm.

When I make a ping from LAN 1 segment 2 I have no ping, but after about 30 seconds of continues ping (ping -t) it start to work perfect. After some time of no activity with the destination host the issue happens again.

Tracing the route packets stops in the last router before the target. This is the first router in LAN 2 after the WAN channel.

In the next screenshot you can see thie issue, the first ping is before a continuos ping and the second one is while continous ping is running.

enter image description here

Thank you in advance
