I have it set with grep -i forwarding /etc/sysctl.d/90-override.conf net.ipv6.conf.all.forwarding = 1 net.ipv4.conf.all.forwarding = 1 in Shorewall lib.private I have setup_sysctls() { echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses echo 0 > /proc/sys/net/ipv4/ip_dynaddr echo 1 > /proc/sys/net/ipv4/ip_forward echo 0 > /proc/sys/net/ipv4/conf/all/accept_redirects echo 0 > /proc/sys/net/ipv4/conf/all/accept_source_route echo 0 > /proc/sys/net/ipv4/conf/all/log_martians echo 1 > /proc/sys/net/ipv4/conf/all/forwarding echo 1 > /proc/sys/net/ipv6/conf/all/forwarding echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter } and in shorewall6.conf IP_FORWARDING=Keep As I understand it this is something that I should be able to setup just in Shorewall. But just in case I also posted the question more generally @ stackexchange, https://unix.stackexchange.com/questions/650410/setting-up-an-ipv6-router-with-two-interfaces-why-is-only-my-configs-lan-n I've tried a bunch of various route additions. I'm just guessing at it. So far nothing I did gets me 'out' that last leg.
