[pkg-netfilter-team] Bug#946519: iptables fails to update rules from fwbuilder

[José L. Fernández Jambrina]

Package: iptables
Version: 1.8.3-2
Severity: important

Dear Maintainer,

   After upgrading to buster from strech, the iptables defined in fwbuilder don't works when changed:
 iall I get is a message "iptables: Chain already exists" for each rule and they don't work.

   Moreover as I removed network-manager package my system start withour rules (maybe with default rules) an this moment the script generated by fwbuilder runs without warnning and rules are applied. Afterwards, if I tried to aplly diferent rules, I get the warnning messages and the rules don't work.

   At first my system was running the stable version of iptables, 1.8.2-4, so I move to the testing version, 1.8.3-2, without changes.

   Thanks in advance,
