This means that the HAVEROUTE column in /etc/shorewall/proxyarp will be removed and the behavior will be like HAVEROUTE=Yes. g) NAT_BEFORE_RULES disappears and the behavior will be like NAT_BEFORE_RULES="No".

Is there a way to mix static NAT and port forwarding or is it only possible to use a rule to port forward other IPs? In my tests using ACCEPT net loc:192.168.134.1:80 tcp http - all This worked if (from outside) I connected to the IP address of the external interface but failed (package went throught to Static NATed machine) for those IPs that used Static NAT.

This is a minor release of Shorewall. WARNING: This release introduces incompatibilities with prior releases. See http://www.shorewall.net/upgrade_issues.htm. Changes are: a) There is now a new NONE policy specifiable in /etc/shorewall/policy. This policy will cause Shorewall to assume that there will never be any traffic between the source and destination zones. b) Shorewall no longer

I have what strikes me as an odd problem with shorewall. Let me describe my setup. My desktop (alfred) is connected to the network through an ADSL modem. I am running rp-pppoe, and this works perfectly. I have a small home network, with two LANs; an Ethernet LAN (including a machine running Windows XP), and a WiFi LAN, including the laptop (william) I am using now. All the computers except for
