Hello, I''m trying to setup DNAT to forward to a PPTP Server behind Shorewall. I setup the PPTP rules per your documentation with tcp port 1723 and Protocol 47 DNAT to my PPTP Server in the local zone. Looking at the logs it is dropping the connection going to port 1723. It is also dropping UDP port 1701, don''t know if it is of any significance. I looked at FAQ 1a and b and the

Hello, Please see the following picture: http://www.wilson-kwok.com/pptp.jpg I used one to one NAT from 210.0.0.1 to 192.168.0.2 for web server, and then use port forwarding from 210.0.0.1 to 192.168.0.3 for pptp server, but I cannot connect from my home to pptp server.

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

Is it possible to pass PPTP packets through 2 firewalls before they hit the remote access server? I installed a Netgear ProSafe VPN firewall as the first line of defense in my network. I have since set up a Fedora Core 2 server running Shorewall 2.1.3 and Squid in non-transparent mode, between the Netgear unit and my network. So, the Netgear faces the Internet with a public, static, IP address.

Hi all, I have a VPN setup but it only works once in a while. It seems my firewall (shorewall 3.0.8) is blocking protocol 47.

Does anyone know if load balancing and DNAT work well together? I know that load balancing and NAT do not, but what about a simple port forward? I can''t apply Julian Anastasov''s patches, because they don''t work with PPTP patches. :/ Anyhow, a simple: iptables -t nat -A PREROUTING -i eth0 -p tcp --dport xxx -j DNAT --to yyy:xxx iptables -I FORWARD -i eth0 -d yyy -p

I made a boo boo in my config and put in this rule #PPTP DNAT net:213.67.241.162/217.209.46.204/32 loc:192.168.221.200 tcp 1723 DNAT net:213.67.241.162/32,217.209.46.204/32 loc:192.168.221.200 47 - And the the following happened.. and I wonder why it didn''t complain?

Hi all! I''ve set up a Linux box with shorewall doing proxy arp as per http://www.shorewall.net/shorewall_setup_guide.htm#ProxyARP the 5.2 (non routed) example. Everything is working great except for one thing, and that leads me to my question: is there a conflict between proxy arp and pptp? I''ve set the apropriate ACCEPT rules to allow tcp port 1723 and protocol 47 to the host

Greetings List Members, I''ll firstly apologise if this isn''t the place that I should be posting this message but here goes. What I want to do is have a VPN (PPTP/IPSEC/CIPE/etc) server, but it must support more than one simultaneous connection. I currently have a PPTP VPN server setup that has port 1723 and protocol 47 DNAT''d through to the internal IP

I have been trying to get DNAT to work and I actually have succeeded too, however, not how I thought it would work when reading through the documentation. 1. No matter what I do I cannot get DNAT to work unless I have an entry in eiter the nat or the proxyarp file. Is that really how it''s supposed to be? I can''t find anything about it in the documentation. 2. Also, in the

Hi, after kernel upgrade to 2.4.23 my existing configuration of shorewal 1.4.8 will not start / it fail on DNAT and/or masq with message: "iptables: Invalid argument" / I founded some similar problems description - see links bellow, but there is no solution how to get work shorewall with DNAT and masq with 2.4.23 kernel. http://www.ussg.iu.edu/hypermail/linux/kernel/0312.0/0268.html

I have some hosts in a DMZ zone with proxyarp. In my local zone I have a host to which I DNAT. I have discovered that I can reach the host in the local zone by attempting to connect to the fw (As expected) or ANY proxyarped host in my dmz zone (as not expected). Is this normal ? (I''ve just discovered that actually the dnated host answers to requests sent to any IP routed to my host!)

Hi all in the ShoreWall community, [please CC me since I''m not on the list] I had been using FIAIF for a little while, and the setup of ShoreWall has been much easier, the config for each operation in one place, and I''m very happy with it. That said, it looks like one of the concepts could be taken a bit further. In this case, it is actions. To get the process started, I
