Release : 8.1.1 and previous to 7.3
Component : SNMP Interface
Customer is utilizing IPV6 for all TCP/IP traffic.
Add an IPv6 firewall rule to allow inbound udp port 161 traffic. (MAKE SURE this new rule is not last in the list of rules as
displayed in the UI -- i.e. below the "DROP ALL" rule -- or else the new rule will have no effect. In other words, after adding the new
rule, drag it above the "DROP ALL" rule and make sure to save the settings with the rules in the correct order.)
The new ipv6 firewall rule should have the following attributes:
Source Address: ANY
Source Port: ANY
Destination Address: ANY
Destination Port: 161
# '-f' is implicitly added by snmpd systemd unit file
OPTIONS="-LS0-6d 161: udp6:161"
