I''ve got what I think is a fairly simple home network configuration with one Linux box functioning as the firewall, VPN server, DHCP server and file/print server. I am having trouble configuring both a VPN server (PopTop) and the firewall rules for a W2K PPTP VPN client. The VPN server runs on the firewall machine and the VPN client runs on a W2K machine behind the firewall. The VPN

It seems to me that ipsecnat tunnel type is not complete. Latest drafts of ipsec nat-traversal use udp port 4500 for nat-traversal communications. (It''s called port floating). That is needed to get rid of ugly ipsec passthru devices. Now ipsecnat opens port udp/500 from any source port. And I think ipsecnat won''t work at all with gw zone defined? I''m not sure about

And it looks like there''s a bug. I have a "firewall" with a single ethernet interface that splits into a network zone and a local zone and as a consequence I have a hosts file with the following in it: net eth0:!192.168.0.0/24 loc eth0:192.168.0.0/24 When I run shorewall start, I get an error, running in debug mode and capturing the output give me: + run_iptables -A

Hello everybody, To make all clear; I am newbee in shorewall, but... I''ve tried to connect two computers by Mandrake Connection Sharing facility. (Mandrake 9.1). Briefly, the problem is that after all that auto-configuration activities the network is completely down, just because shorewall. The result of calling `shorewall debug start` by hand is available at the end of the

Hello! I configured a pptpserver on my firewall and followed the pptp-manual from Shorewall. Login via VPN to firewall (internal ip: 192.168.10.2) is ok and I can ping this server via internal ip (and use it: add samba-shares, etc.). Unfortunately I can''t connect to other hosts in my intranet (LOC). Ping from vpn-client to clients in intranet fails, although Shorewall-Log shows an

hello , i''m currently trying to set-up Traffic Shapping with Shorewall and I have strong feelings that I found a bug. I may be mistaken, but I tried everything and can''t get it to work. I''ve turned ON TC_ENABLED=Yes and CLEAR_TC=Yes when i start shorewall ( shorewall start ), i get this message : Setting up Traffic Control Rules... TC Rule "2 eth1 0.0.0.0/0 tcp

Hi guys, I''m trying to setup an IPIP tunnel between a Cisco router and a firewall running Debian GNU/Linux Sarge with Shorewall 2.0.13. I''ve read and implemented the http://shorewall.net/IPIP.htm document, but I don''t understand why there should be at the same time a "tunnel" and a "tunnels" script. Shorewall still refuses to let the

Dear list members, Masquerading does''not work for me. This is a Mandrake Linux 10 system, but I use another kernel, that included in the original distribution (original: 2.6.3, now used 2.6.8 because of a lot of suck with OpenSwan with kernels prior 2.6.4). The problem seems to be similar or identical mentioned here:

Hi Tom, I nearly completed the test and installation related to http://www.shorewall.net/PPTP.htm. However, there is no serious problem when it is operated as it is in the general companies, but there is Client Program for MS-Window that is operated only by Public IP. So I am very concerned about it. I would like to use Internet through Gateway in (B) as local computers in (A) receive Public
