UPNP external IP problem on v3.30

RouterOS General
1

I have a problem here with UPNP on v3.30, RB532A.
The external connection is PPPOE, and it reconnects after 7-8 days, getting a new public IP address.
But the UPNP does not set the NAT rules with the actual external IP, it sets a previous one (probably the IP the interface got the first time).

Problem can be solved by disabling then enabling the UPNP service, but it’s back when the external IP changes again.

Any ideas what’s wrong? Maybe a bugfix in the next release? (:

/ip upnp print 
                           enabled: yes
  allow-disable-external-interface: no
                   show-dummy-rule: yes




/ip upnp interfaces print detail
