ADSL router, two nics, web server not visible from internet
I have an ADSL router, a linux box with two NICS connected to the router and another PC connected to the router. I installed shorewall using the two interface method. I can ping and see the webserver on the linux box from the local network, but not from the internet. Sys info as follows: [root@wilma root]# shorewall version 1.4.6b [root@wilma root]# ip addr show 1: lo: <LOOPBACK,UP> mtu

Shorewall problem, perhaps with PPPoE
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

SFTP
(anonymous post) I have a simple 2 interface firewall setup and all is good, almost. I am hosting virtual websites and DNS behind shorewall no problem. However I am trying to use SFTP via a different port number and have no luck even though Putty works well. Is there anything weird to sftp and shorewall? My lab uses a different firewall (firestarter) and it works OK. I am using; DNAT net

DNAT not working after changing BIND to use views
Hello all: I''ve got a confusing issue. I had a working shorewall configuration (based on the two interface model) using DNAT for redirection to my HTTP server. The HTTP server is on my inside network (I know - bad juju, but one thing at a time). I changed my configuration this morning to use views in my BIND (named) configuration. Everyone outside the firewall is able to get in

Unknown commments in shorewall status.
I wonder if someone can tell me what these ''unknown'' remarks mean in my status file. They are only in the last portion of the file and are listed below. If they mean nothing, I will rest easy. But if not it means I need to fix something. Your thoughts would be appreciated. ---------------- udp 17 92 src=24.224.173.220 dst=24.222.0.75 sport=1027 dport=53 src=24.222.0.75

Proxy Arp Ip Conflicts
I must have something configured wrong somewhere. I''ve enabled proxy-arp on my shorewall 2.0.7 firewall. Works fine for what its supposed to do, I can see all the machines through it great. However, whenever its enabled, the network on the DMZ goes screwy. I''ve narrowed it down to this: when proxy arp is enabled for that interface, like such: echo 1 >
