I have 5 watchguard firewalls and all links to them are responding the same since we upgraded the firmware on the firewalls. I have verified all of them on the test map with the same results. I was searching some more on the forum and found this

Do you think that the upgrade changed the counters to 64 bit and this is the problem. If so, can you provide some assistance in building a new function as described as I am not very good with snmp at all.
Thanks
