Hi, I am working on this issue as well with SavLou,
Iptables and ip6tables are usually used on Busybox for firewall rules, but they are not even installed / running on the hosts.
So no, no firewall logs…
The ICMPv6 NDP "neighbor solicitation" (type 135) is properly sent from host A as monitored on host C, but device B never gets any packet. All are connected on an IPv6 capable switch.
It is as if device B does not receive IPv6 multicast packets.

SHOREWALL6-PROXYNDP(5) [FIXME: manual] SHOREWALL6-PROXYNDP(5)
NAME
proxyndp - Shorewall6 Proxy NDP file
SYNOPSIS
/etc/shorewall6/proxyndp
DESCRIPTION
This file was added in Shoreall 4.4.16 and is used to define Proxy NDP. There is one entry in this file for each IPv6 address to be
proxied.
The columns in the file are as follows.
ADDRESS - address
IPv6 Address.
INTERFACE - interface (Optional)
Local interface where system with the ip address in ADDRESS is connected. Only required when the HAVEROUTE column is left empty or is
set to no or No.
EXTERNAL - interface
External Interface to be used to access this system from the Internet.
HAVEROUTE - [-|Yes|No]
If there is already a route from the firewall to the host whose address is given, enter Yes or yes in this column. Otherwise, enter no
or No or leave the column empty and Shorewall will add the route for you. If Shorewall6 adds the route, its persistence depends on the
value of thePERSISTENT column contains Yes; otherwise, shorewall6 stop or shorewall clear6 will delete the route.
PERSISTENT - [-|Yes|No]
If HAVEROUTE is No or no, then the value of this column determines if the route added by Shorewall persists after a shorewall6 stop or
a shorewall6 clear. If this column contains Yes or yes then the route persists; If the column is empty or contains No or no then the
route is deleted by shorewall6 stop or shorewall6 clear.
EXAMPLE
Example 1:
Host with IPv6 2001:470:b:227::44 is connected to interface eth1 and we want hosts attached via eth0 to be able to access it using that
address.
#ADDRESS INTERFACE EXTERNAL
2001:470:b:227::44 eth1 eth0
