Description
Traffic leaving the firewall to the net has to be masqueraded (SNAT) to wan ip address regardless of where it is coming from.
Now, we masq only traffic coming from the lan network.
Additional lan (local networks, extra zones) can't reach the net.

After update, /etc/shorewall/masq should contain only your wan eth, i.e.:
###################################################################################################### #INTERFACE:DEST SOURCE ADDRESS PROTO PORT(S) IPSEC MARK USER/ SWITCH # GROUP eth1
without references to networks under source column.
Also,
]# shorewall show nat | grep MASQ 38 2633 MASQUERADE all -- * * 0.0.0.0/0 0.0.0.0/0 policy match dir out pol none

VERIFIED
Before update, in /etc/shorewall/masq:
#INTERFACE:DEST SOURCE ADDRESS PROTO PORT(S) IPSEC MARK USER/SWITCH # GROUP eth1 192.168.8.0/24
And:
# shorewall show nat | grep MASQ 0 0 MASQUERADE all -- * * 192.168.8.0/24 0.0.0.0/0
After update I've got the expected config file and command output.
