Hi ! Recently i switched my internet provider, to get more speed but another braindead setup regarding public ip addresses. I now have 4 PPTP Tunnel available, of which i''m using one as the gateway ip doing masquerading to other machines in my local lan, excluding three other machines, which i would like to use 1:1 nat to get them a direct access to one of the pptp tunnels. I was

I have a Cisco VPN Concentrator 3000, It has the ability to auth PPTP tunnels off of a WinNT Domain controler. Well, I to use my samba3 box instead of a WinNT box. I have samba3 running off of an LDAP back end. Anyway, I setup the VPN Concentrator to auth off of the samba box, and when I test it with the test option, and it works, but when I try to auth a pptp tunnel, it fails saying the

Last question, I promise, I am running PopTop for PPTP on the same box as my firewall. I can connect to the box fine, but nothing will route between the VPN tunnel and the local hosts. I read the Some Hosts have Special Firewalling Requirements article and though it was what I needed, but either I don''t get it, or it doesn''t apply to me. Here is my config: Zones: #ZONE

Hello, We can't connect to our pptp server through our CentOS gateway with a XP client. The linux client is working but not the XP client. I know for a fact that the pptp server is not the problem because if I connect the XP machine directly to the Internet the pptp vpn is working. I know about the pptp-conntrack-nat patch, I compiled the 2.4.9 kernel, with patch-o-matic-ng-20060511.tar.bz2

I have a centos 4 i386 machine that works like a router (iptables filter, NAT) with two NIC''s. One NIC is connected to my ISP (100 Mbit FTTH), I get a DHCP assigned public IP that changes "sometimes". Most incoming ports are blocked by my ISP. In order to get a fixed IP and open ports, I have to set up a PPTP tunnel to the ISP. The default gw and the NAT''ing goes to

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

Hi All, Anyone else seeing this. Just updated to kernel 2.6.32-504.12.2.el6.x86_64 and pptp vpn (invoked via Gnome Network Manager) fails to connect. Boot up the previous 2.6.32-504.8.1.el6.x86_64 and pptp all good. OpenVPN is not affected. Anyone else seeing this. I have log file details if anyone wants those. Don't see it reported elsewhere.

Hi, All I'm tring to get a client connected to a vpn server running pptp & centos, the client connects to the server but I can't browse the internet or the local network from the client, when I stop the firewall the client can ping the server but no browsing can be done, do I need a iptables rule to allow pptp clients to use the internet or browse the network???

Hi All, This is a general VPN question; PPTP VPNs seem to be very easy to set up with CentOS as the VPN server and the built-in windose client, but how do list members feel about the security vunerabilities reported with the MS implementation? Specifically the 6 problems reported here : http://www.schneier.com/pptp-faq.html or maybe im being paranoid? Would any of you roll this solution out

Hello, anyone can help me to masquerade realplayer and PPTP ? I have one linux gateway (2 NIC's) and W98 in my 192.168 internal net. No computer in 192.168 net can listen radios (using browser) or connect to PPTP server outside 192.168 net(internet). Thanks any help, Mauricio.

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

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

The problem scenario I describe was reported previously in the Shorewall lists but its resolution does not seem to have made it into the lists. Scenario: Windows XP client seeking to establish a VPN connection to a Windows 2003 Server located behind a Shorewall firewall (running on Mandrake kernel 2.4.22-37mdk). The connection cannot be made, the client reports error code 721. Discussion:
