Unable to ping to other with the same subnet

[luckyle]

Hi,

I have been using 2.0.1-RELEASE (i386) for three weeks but i did not know why it sometimes can not ping to my load balancer while it has the same subnet.

Load balancer: 192.168.1.1
pfSense:        192.168.1.4

and my output as below.
2.0.1-RELEASE][admin@pfsense.local]/root(33): ping -S 192.168.1.4 192.168.1.1
PING 192.168.1.1 (192.168.1.1) from 192.168.1.4: 56 data bytes
ping: sendto: No route to host
ping: sendto: No route to host

Everything will be okay after rebooting the pfSense finishes.

Please advice me anything.
Thanks,

What is the NIC chip manufacturer?

[luckyle]

it's D-link.

If they are not onboard, I would change them to Intel if you have them.

Thanks for your reply, I will try to replace them…
