I cannot ping directly connected hosts from another network ?

[jordan-jj]

Hello 

  I have two hosts connected to the same router  in different network . I can ping to their gateway but not to hosts directly.

please see the image below

Server 1 Ip :50.50.50.10/24 . GW =50.50.50.1 

hosts :30.30.30.30/24    GW;30.30.30.1

HOw to make it work

your hosts dont have a default gateway, or at least on of them.

see if you can ping 50.50.50.1 from 30.30.30.30 for instance and from the 50.50.50.10 to 30.30.30.1

please rate if this helps

hosts can ping  to both end of the router , but from hosts its not pinging

Share router config...

Any ACLs?
Subnets and masks are correct?
Can you ping hosts from router? Using both interfaces as source?
Default gateway on the hosts?
Disable windows firewall if you are using windows hosts.
ARP correct on all hosts and router?

[jordan-jj]

1) No  ACL

2) yes

3) hosts can be pinged from router

4) yes

5) i am in packet tracer

6) how can i check arp in router and hosts

[mile.ljepojevic]

Routers: "show ip arp"

Hosts (Windows): arp -a

Not sure about linux but fairly sure it can be googled out...

To be honest, I don't think it's an ARP issue, that should just help us determine if something of the above items was not correct.

Also, item no 3): can you ping from the router using source command? Like ping 30.30.30.30 source 50.50.50.1 (IP address of the router)?

Then vice versa. Also, from both hosts try to ping both router interfaces... If all that works, I won't be able to help you without really looking into it, since these are "most usual" issues, and if this is all good, then I need to snoop around to see what's there...

Hi

Could you please provide a traceroute? the hosts have a gateway configured? Also is possible to share the config of the multilayer and router?

Have you configured any routing protocol like EIGRP or OSPF, o are you using static routes?

Thank you
