Thanks, but I tried this already. It causes bsnmpd to listen on the
given IP as well, but doesn't remove the *:* entry:

root at gw1 [/root]# sockstat -l4
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
root     bsnmpd     61251 4  udp4   *:*                   *:*
root     bsnmpd     61251 5  udp4   127.0.0.1:161         *:*

The author suggested using "begemotSnmpdPortTable.0.0.0.0.161 = 1" and
change the IP there, but this causes the following error:

Apr 30 08:59:59 gw1 snmpd[78798]: unknown variable
Apr 30 08:59:59 gw1 snmpd[78798]:   in file /usr/local/etc/bsnmpd.conf line 20
Apr 30 08:59:59 gw1 snmpd[78798]: error in config file
