Hi Tom,
trying the port forwarding/NAT as discribed in
shorewall-4.4.11.2/html/FAQ.htm#DNS-DNAT
#shorewall version
4.4.11.2
#grep PPP /etc/shorewall/rules
DNAT loc loc:10.10.1.55 tcp www - $PPP0_IP
#grep PPP /etc/shorewall/init
PPP0_IP=`find_first_interface_address ppp0`
The method works fine when PPP0_IP is set from the params file, but fails on
'shorewall restart' if tried from the init script
#shorewall trace restart
