Package: iptables
Version: 1.8.2

Hello, friends!

In Devuan 1, Devuan 2, Devuan 3 (and Debian, and Ubuntu) have next 
standard issue with *iptables*!

The current range of values for the *--tcp-option* /iptables/ flag is 
1-255 - this is not correct. The correct range of values should be 
0-254. Please read the following information: 
https://www.iana.org/assignments/tcp-parameters/tcp-parameters.xhtml#tcp-parameters-1 
This negative change in /iptables/ was made approximately 2 years ago 
without making this change public. Please report this issue to the 
/iptables/ developers so that they can set the range of --tcp-option 
values in accordance with the accepted standards for the TCP Protocol.

Please see: https://dev1galaxy.org/viewtopic.php?id=3347
