similar to: PPTP VPN secure?

I''m considering adding a seperate subnet to my loc network making loc1 (192.168.1.0/24) and loc2 (192.168.0.1/24) with the goal of seperating my wireless traffic from my wired LAN traffic. Has anyone had success doing this, or is it still possible to sniff the traffic of a seperate zone on the same interface with tools like ettercap?

I''m very new to shorewall. My setup is IP Gateway (CentOS 4 + Shorewall) with 3 NIC cards. Shorewall works great on the firewall machine. Bind also works (local net machines get IPs fine). Under firestarter, all works great. With shorewall, the loc machines can not route past the firewall. They can connect to the firewall, but not past it. Exactly what information should I post to get

I want to add two IP ranges on one NIC card (eth0 and eth0:1). Has anyone done this before? The CentOS 4 gui keeps locking up when I try it there and the command line ifconfig seems to work, but ifup always returns the error that is never heard (no such device) of eth0:1 thanks

Dears, I have two questions 1-Is there a way to export fax tiff file image from .pcap captured file . In other words i am trying to backup all faxes that are passing on my network,and export the fax file later on. Is this feasible and how . i am using sip protocol and fax protocol is bypass ,G711 i can use T38 if that will solve the matter. 2-I tried using asterisk to receive the

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

Everytime I try to recompile a kernel, "make modules" always dies with the error: mv: cannot stat `include/asm-i386/asm_offsets.h.tmp': No such file or directory make: *** [include/asm-i386/asm_offsets.h] Error 1 I installed the src RPM and kernel-devel ... any ideas as to what I could be doing wrong? Thanks!!

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

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 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, I am trying to get samba to work over a pptp link to win9x boxes. I have the pptp link working, but I am unable to get at the shares. Could someone point me in the direction of documentation about the best way to set this up. Thanks Jeff Meeks jmeekssr@net-serv.com

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

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:

Any recommendations for a Linux distro to put Shorewall on top of? My main concern is to be able to use a Windows NT PPTP VPN server behind the firewall. If I remember right, there were some issues with passing GRE traffic through some versions of the Linux kernel. Are they solved now or do I still have to do some cryptic kernel patches? Experiences with that? Thanks! Tim
