This bug was fixed in the package ufw - 0.36.2-1
---------------
ufw (0.36.2-1) unstable; urgency=medium
* New upstream release (LP: #1946804, LP: #1927737, LP: #1927734,
LP: #2015645, LP: #1996636, LP: #1965462, LP: #1951018, Closes: 1034568,
Closes: 1034119). Drop the following (included upstream):
- 0002-fix-copyright.patch
- 0003-python3-versions.patch
- 0004-set-default-policy-after-load.patch
* Remaining changes:
- 0001-optimize-boot.patch
* add new debian/po/ro.po. Thanks Remus-Gabriel Chelu (Closes: 1033758)
* debian/control:
- Breaks with iptables-persistent and netfilter-persistent. When ufw is
installed, it is not enabled by default, so it doesn't interfere with
other firewall software (until it is enabled). In contrast,
iptables-persistent and netfilter-persistent install enabled, which
interferes with ufw. Add a breaks on these to avoid them being
co-installed with ufw (and causing problems for users).
- use Python-Version instead of XB-Python-Version
- remove Depends on obsolete lsb-base
* ufw.lintian-overrides:
- update for breaks-without-version iptables-persistent and
netfilter-persistent
- update for newer lintian

Title:
No ability to discern IPv4 vs IPv6 rules through Python
Status in ufw:
Fix Released
Status in ufw package in Ubuntu:
Fix Released
Bug description:
Version: ufw 0.36
Ubuntu Version: 20.04.3 LTS
There doesn't appear to be a Python method for accessing IPv4 and IPv6
rules in a distinguishable manner.
In the source code (root/src/backend.py) there is an object that
stores IPv4 and IPv6 rules in separate lists. Those lists are then
accessed with the following method:
def get_rules(self):
'''Return list of all rules'''
return self.rules + self.rules6
The issue with this is that the returned list doesn't contain an
indication of what IP version each item corresponds to and would
display something like the following.
1 allow 22/tcp
2 allow 80
3 allow 443
4 allow 22/tcp
5 allow 80
6 allow 443
I don't currently see a way to distinguish between IPv4 and IPv6 rules other
than accessing the lists in the backend object directly (but I don't think this
is best practice). E.g.:
rules_ipv4 = backend.rules
rules_ipv6 = backend.rules6
One possible fix would be to add functions that return only the IPv4 or IPv6
rules. E.g.:
def get_rules_ipv4(self):
'''Return list of all ipv4 rules'''
return self.rules
def get_rules_ipv6(self):
'''Return list of all ipv6 rules'''
return self.rules6
