I believe so.
# cat /proc/sys/net/ipv4/ip_forward
# iptables -L -n
ACCEPT all -- 0.0.0.0/0 192.168.219.0/24
REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with
To be sure that the firewall was not the source of trouble I temporarily
turned it off and observed no change in behaviour from that previously
Another correspondent pointed out that I may need to run routed to
propagate the routing information from the host to the network.

So, I will look into this.
Thanks for the help.
