I was

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, 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

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

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

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. Thanks Ken -- This message has been

Hi there.... Has anyone seen a tutorial around for a pptp server (on the same server as the firewall) for centos/rhel 4? I have been following a few general tutorials for POPTOP, but nothing seems to really work as of yet. Thanks! -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi I've been using linux to give VPN access to my corporate LAN using the following software: Centos 5.2 x86 kernel 2.6.18-92.1.18.el5xen pptpd (poptop) 1.3.4 ppp 2.4.4 The Centos server has directly connected the Internet Router, on one interface (eth1) and the LAN on another (eth0) and it works as the firewall/VPN server of my LAN. It mostly works, however, if I try to connect using

Hi all, I´m running a server that frecuently needs to open a pptp session with a remote server outside my Company. This server is running behind a Shorewall firewall and I don´t find information in Shorewall web page because there is no information in the link http://www.shorewall.net/PPTP.htm#ClientsBehind Nowadays I can connect this server with the remote one but te session is closed after

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 have two/three PPTP servers on my network and each one of them are on their own subnet and I want to be able to send traffic to each and everyone. My rules file entry is as follows DNAT net loc:1.1.1.1 tcp 1723 DNAT net loc:1.1.1.1 47 and DNAT net loc:2.2.2.2 tcp 1723 DNAT net loc:2.2.2.2 47 however all the traffic only goes to 1.1.1.1 because its the first DNAT entry. I tried the

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:

How to setup a vpn server on centos? I can't find the pptpd in any repo

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

Hi, can you tell me how to set up routing of packets comming from pptp clients connected to my FW. For now I managed to initialize the vpn with ppp+ byt I can''t MASQ it in the /etc/shorewall/masq file. I entered there this: eth0 eth1 and pptp is working fine but now everybody can change thair IPs and get Internet. How exactly should I set it up. I am running shorewall o n

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
