Hello, I've the following configuration: Internet <=> Host with fixed IP <=> OpenVPN Tunnel <=> Firewall Host with dynamic IP <=> DMZ
Firewall Host with dynamic IP isn't the gateway. I've configured: 1.) "Host with fixed IP" a DNAT forward into the OpenVPN Tunnel (OK): SMTP(DNAT) net vpndmz:192.168.x.y SMTP(DNAT) $FW vpndmz:192.168.x.y 2.) "Firewall Host with dynamic IP" forward into the DMZ again: SMTP(DNAT) vpndmz dmz:192.168.x.y Everything works fine except the shorewall rules on "Firewall Host with dynamic IP". Packets go from "Firewall Host with dynamic IP" to DMZ, responses from DMZ go back to "Firewall Host with dynamic IP" but then they are not routed into the OpenVPN Tunnel back again but to the default gateway (which is of course not working). I read already http://shorewall.net/MultiISP.html, http://shorewall.net/PacketMarking.html and http://shorewall.net/manpages/shorewall-route_rules.html and some other sites but I still didn't get a working version. What's the recommended way? Via mangle? Via multiple providers? What I've tried so far (config partly listed): ERROR: A provider interface must have at least one associated zone /etc/shorewall/providers /etc/shorewall/mangle MARK(2) vpndmz dmz /etc/shorewall/providers p_main 1 1 - eth0 detect track,balance p_vpn 2 2 - tun36 detect track,optional,loose /etc/shorewall/zones dmz ipv4 vpndmz ipv4 p_main ipv4 p_vpn ipv4 /etc/shorewall/interfaces dmz DMZ_IF tcpflags,nosmurfs,routefilter,logmartians,physical=eth2 vpn TUN_IF tcpflags,nosmurfs,routefilter,logmartians,physical=tun0 vpndmz tun36 tcpflags,nosmurfs,routeback,logmartians,physical=tun36 If something is unclear, just ask. BTW: Please have a look at the Port Knocking patch :-) Thank you.
