Bug ID: 249972
Summary: Trusted hosts on rc.firewall are only trusted in one
direction
Product: Base System
Version: 12.1-RELEASE
Hardware: i386
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: conf
Assignee: b...@freebsd.org
Reporter: archit.s...@gmail.com
I attempted to configure an IPSec transport mode connection between a host and
a trusted peer (e.g. 10.0.1.2) using the "workstation" mode ipfw firewall. The
firewall appears not to have allowed outgoing packets. The following diff
address the specific test case I had and appears to be consistent with the
concept of a trusted peer.
> diff /etc/rc.firewall /tmp/rc.firewall.diff
516c516
< ${fwcmd} add pass ip from $i to me
---
> ${fwcmd} add pass ip from $i to me keep-state :default
Alternatively, a second rule per trusted peer could be added to pass packets to
the peer ("${fwcmd} add pass ip from me to $i").
Configuration example below:
firewall_enable="YES"
firewall_type="workstation"
firewall_myservices="22,80,443/tcp"
firewall_allowservices="0.0.0.0/0"
firewall_trusted="10.0.1.2 10.3.4.5 10.6.7.8"
