Hi guys.
My problem is with my new 1921 router.
GE0/0 192.168.0.253 255.255.255.0
GE0/1 192.168.1.253 255.255.255.0
2 PCs directly connected
to 0/0 192.168.0.1
to 0/1 192.168.1.1
Both side can't comunicate each other. I can ping router interface. From router console i can ping both machines, but cannot ping from one pc to other. It is my first cisco console manage router. Maybe i've made something wrong. is there any monitor to check online packets.
I've checked same conf on cisco packet tracer (router 1941) and everything works fine.
There is no access-lists yet.

Hi
Router IP TRAFIC INTERFACE during ping.
13 no route ?
GigabitEthernet0/0 IP-IF statistics :
Rcvd: 16 total, 1086 total_bytes
0 format errors, 0 hop count exceeded
0 bad header, 13 no route
0 bad destination, 0 not a router
0 no protocol, 0 truncated
0 forwarded
0 fragments, 0 total reassembled
0 reassembly timeouts, 0 reassembly failures
0 discards, 3 delivers
Sent: 13 total, 728 total_bytes 0 discards
13 generated, 0 forwarded
0 fragmented into, 0 fragments, 0 failed
Mcast: 0 received, 0 received bytes
0 sent, 0 sent bytes
Bcast: 5 received, 0 sent
Firewall excluded (both ip's reposnding from routers console)
There is no icmp packets in wireshark when pinging from PC to PC
I think that problem is with packets forwarding, so maybe arp table is incorect, maybe no acl or empy access-list is deny by default. I have no idea.

I've added gateway (ip route 0.0.0.0 0.0.0.0 "adress" metric)
PC with same network as gateway is passing, the other one has no internet access.
