[Labs-l] Cannot connect to DB

[Nuria Ruiz]

Team:

All of a sudden, wikimetrics (a popular tool deployed to labs:
https://metrics.wmflabs.org/)
cannot connect to the labs database, this happens when there are firewall
or IP tables issues as it looks like ip tables rules are not on puppet.
However we have tried to apply the older rules we had to no avail. If
anyone could she some light as to what is going on here it will be great.

Please see set of rules applied below.

Thanks,

Nuria
