Hey All,
Having a weird problem: We have an installation of IPSwitch WhatsUpGold which uses SNMP to monitor network resources.
I have noticed in our daily logs that the IP for the WhatsUpGold server has been showing a lot of dropped packets, so when I investigated I saw that a lot of traffic going out to destination port 161 was being blocked.
So I thought I would correct that by allowing all traffic to port 161 bound for our internal networks, no big deal.
Well, that took care of some of the problem.. When I look at the livelog, I now see UDP traffic directed at port 161 is allowed and references the packet filter rule I created, but we are also still getting Default DROP packets labeled SNMP traffic (not UDP) here is an example:
15:55:59 Default DROP SNMP 172.22.2.142:52709→172.21.22.1:161
15:56:00 Packet filter rule #3 UDP 172.22.2.142:52741→172.21.22.2:161
The first packet is dropped, the second one is allowed... can anyone help?
