RE: [libreoffice-website] RE: Infra call on Tue, May 18 at 16:30 UTC

Hi Guilhem,

My IP lists are sourced from my pbx of malicious ip's trying to exploit the pbx. Also have 
Wordfence of ip's trying to brute force my wordpress sites and cpanel of ip's trying to brute force 
my server. I don’t think that such IP's are an issue to share.

Prior to the firewall migration wouldn’t it be better to get an IDPS system in place and move the 
rules over once such a system is in place such as snort?

It's probably best to schedule another call during the coming days or weeks.  We'd need to convert 
the existing shorewall-based firewall policy rules to nftables, and come up with a smooth upgrade 
path.

ipset replacement is trivial ‘set NAME { type ipv[46]_addr; [timeout 10m;] }’
but that's not the focus here given we don't make use of ipsets in the first place.  Also we likely 
can't exchange IP lists for privacy reasons.  I think dynamic sets populated on the fly by the IDS, 
and automatically released after some minutes, would be fine :-)

Cheers,
