192.168.1.37 can ping 192.168.0.22, but can't ping 192.168.0.240
subnet masks are 255.255.255.0 on all hosts in question
Switch/gateway in the middle (192.168.1.253) can ping both of these addresses, and it also contains a correct ARP entry for 192.168.0.240
When I run tracert on 192.168.1.37, pointing to 192.168.0.22 I get a tracert response:
1 1 ms <1 ms <1 ms 192.168.1.253
2 <1ms <1 ms <1 ms 192.168.0.22
But there is no tracert response when I point it to 192.168.0.240. When I check the wireshark trace for ICMP responses - there are none! Looks like the gateway is not responding to ICMP packet sent to that remote address at all.
What else can I check? Any ideas?
UPDATE: Both 192.168.0.22 and 192.168.0.240 have the same default gateway defined. I can ping 192.168.1.37 from 192.168.0.22 but not from 192.168.0.240
UPDATE 2: When I change IP address on the 'difficult' host from 192.168.0.240 to 192.168.0.34 everything works well! When I change it back to .240 it stops responding to pings from the other subnet. What is causing it? We are running a bit short on IP addresses, so it would be good to know why .240 doesn't work.
