We are running a Nokia IP330 3.3 SP3. We've found that if we set
up four servers in the DMZ to constantly ping a server in the internal
net, everything will work for hours, then suddenly all four servers will
fail to ping for about 10 seconds, and all at the same time. Then it all
comes back again. This will happen every few hours, but with no regularity.
The stats through Voyager show no excessive interface errors, no interface
resets, nothing looks wrong.
Everything is NAT'ed manually, no auto-Nat. Firewall1 logs show nothing
unusual. All translated source and destination addresses are correct.
We eliminated all switches and hubs between these two networks as to being
the problem.
There are no duplex mismatches with any of the devices.
So now I am thinking that there is something going on deeper in
IPSO. I am reading up on running debug in IPSO to give me more
information, but I was wondering if anyone out there has any good debug
commands for me to try or anything in particular to look for? Any help
would be appreciated. Thanks.
Scott
