Bird BGP Not working when CSF Enabled
Posted: 08 Dec 2022, 19:29
Hi all,
I am rebuilding my infrastructure and those services facing the public, I am opting to use CSF instead of vanilla IPTables.
I am having a bit of an issue when CSF is active Bird2 is failing to work properly, I was wondering if anyone else has had this issue before and solved it.
The error I get is:
Announcing my own IPV4 and IPV6 ranges from another VPS on the private lan.
enp1s0 is public net enp6s0 is private net
contents of /usr/local/csf/bin/csfpost.sh
iptables -n -L -v --line-numbers shows that the rule is getting added in a different place than anticipated, so maybe that's the cause.

BOGON filtering is disabled on enp6s0 as it runs on the 10.8.96.0/20 range.#!/bin/bash
/usr/sbin/iptables -I INPUT 8 -i enp6s0 -p ospf -j ACCEPT

iptables -n -L -v --line-numbers shows that the rule is getting added in a different place than anticipated, so maybe that's the cause.
Any hints would be apreciated I need to be able to anycast the service on this machine.Chain INPUT (policy DROP 0 packets, 0 bytes)
