It isn't capable.

The net-snmp package, available on pfSense 2.4, does support IPv6 SNMP.

Are we talking about the same net-snmp package? (

"SNMP is a suite of applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both IPv4 and IPv6"

The SNMP daemon built into pfSense is bsnmpd, which is not capable of using IPv6 right now.

On 2.4 we have an additional package for net-snmp, which is the one you linked, and it can handle IPv6 SNMP.

Sorry. I totaly misread your sentence. I'll close this as it will be fixed in 2.4 and is not capable in 2.3 [edit] I can't close this :/ This can be closed [/edit]

Marcel Kallinger Hellwig: We just upgraded to pfSense 2.4.2 but snmp is still not listening on IPv6. Is the solution to manually install net-snmp? And if so, how can we make it run? We just installed net-snmp and could not make it listen at all. More information on how to get net-snmp running on pfSense would be helpful in this case.

Yes, use net-snmp. This is not the place for discussion or instruction, however. Post a thread on the forum, mailing list, or pfSense subreddit and someone can help you get net-snmp going.
