I have a clearos gateway linux working as gateway. I have some problems with the conectivity, everything works great but for a few seconds internal ethernet stops working. After 5-10 seconds, it works again.
I did a ping to internet and from the gateway I didn't find any packet lost, but from a computer in the intranet I get some problems:
Request timeout for icmp_seq 94
92 bytes from mygateway.ar7 (192.168.1.1): Destination Net Unreachable

This is my ifconfig eth2

What can be the problem? Local DNS server? Switch? Network loop?
Any idea?
Thanks!
