The upstream provided DNS servers are populated correctly in resolv. However, ip -6 show route doesn't have any gateway listed:. However, my expectation is that when the ppp0 interface comes up, the route should be autoconfigured, along with the prefix, DNS servers and everything else. IPv6 routing works on pfSense 2.
Do I need to manually add this route each time ppp0 comes up, or should this automatically work? I've got a debian Linux box doing almost the same thing I don't use a dhcpv6 server and I'm using dibbler as the ipv6 dhcp client for the ppp interfacein my PPP config I've got:.
I suspect you're missing the defaultroute option. To ensure that kernel config params are really set everytime the ppp device comes up try to use a udev rule:. Could you capture interface ppp trace with tcpdump during ppp negotiation so you can see if ipv6 adress is being provided by RAS?

If you only wish communication to work between the PPTP connected hosts server and clientit's easy. Both sides of the tunnel have an IP and you should be able to reach the other side when you are connected.
Slightly more advanced is if you have one computer connected to a server and want to reach computers on the server's LAN. If this is the case, you will have to set up a route to the other network after the tunnel starts. In the figure above: the tunnel from the client to the server is ppp0, the remote network uses addresses starting with So after the tunnel starts, add this route: route add -net Packets addressed to the tunnel server itself will still use the interface route created when the tunnel started.
If you have other computers connected to your computer, in a local area netowork LANyou may want them to be able to connect to the remote network. Like this:. If you wish to reach any computer on the other side of the tunnel, from any computer on your LAN, you will also need to set up a routing on the foreign LAN, or use ipchains or iptable to do address translation.
In the figure above, the important information is: the remote network is The solution depends on the kernel version. This is a special case when you are running a workplace tunnel within an ADSL service provider's tunnel.
Also, the file should be executable! Some sites configure their PPTP server to give to the server end of tunnel the same IP address that is used to contact the public interface of the server.
When this happens, it isn't practical to use simple routing. In the figure above: the link from the client to the internet is ppp0, and has an IP address at the client of PPTP Client.
Client to Server If you only wish communication to work between the PPTP connected hosts server and clientit's easy. For example: ifconfig ppp0 grep inet inet addr The remainder of this section covers alternate methods. Replaced primary interface name in ip-up. Reported by Jeff Nelson.In this article I show you how to configure PPP for the most common type of connection.
We assume your Linux machine is a stand-alone machine that dials into an Internet Service Provider and performs an automatic login, and the Internet Service Provider allocates the IP address that your machine will use. You will need the right software and a couple of pieces of information before you start.
Let's get started. First, check that you have the right software. The program that manages PPP for Linux is called pppd. The pppd program is linked very tightly with the kernel, so you must run a version of pppd that matches your kernel. If the first command fails, you probably don't have PPP installed. You can obtain the latest version of the source from:.
If you have installed from a distribution such as Debian, Red Hat or Slackware, the pppd program is available precompiled within those distributions. You just have to get the package and install it. Next you must note what keystrokes you will send and what prompts you will receive to log in to your ISP. The best way to collect these is to try manually logging into your ISP using a terminal program such as minicom.
Lastly, you must know the IP address of a nameserver so that you can configure your name resolver and use host names instead of IP addresses. Get this information from your ISP.Port 873 rsync exploit
The pppd program can accept configuration parameters from two places. The arguments supplied are close to identical in either case, but the command line method can be messy. So I will describe how to configure PPP using the options files instead. The options file is a simple text file containing parameters pppd will use when it is executed—one parameter per line. The options file must be readable by whoever will execute the pppd program. In most installations this will be root, either directly or by executing pppd from a program like sudo.
These are all fairly typical defaults for an ISP connection. You will have to adjust the serial device to suit where you have your modem connected and, if you are using data compression, you might want to set your serial port speed to something higher.
PPP provides a means of escaping select characters, so that they do not interfere with your connection. For example, if you were running PPP over a link that would disconnect if it received a control-D character, you could ask PPP to escape that character, and it would automatically replace it with another and reverse the process at the other end.
While the default is safe, it escapes a number of characters that normally don't need escaping and this will decrease the performance of your link.
Since most ISPs provide 8 bit clean links you don't need to escape any characters, so we tell pppd not to, using the asyncmap option.

The pppd package includes a program called chat. The chat program is a simple program that can be used to automate the dialing procedure.
The chat program also accepts arguments from the command line or from a file. Again I'll describe how to configure it from a file as this is the better method. To make use of the chat program from within pppd, we must ensure that the connect option points to a script that calls chat.
This shell script will invoke the chat command with the -v-t and -f arguments. The -v argument is useful when you are configuring pppd, as it sends verbose diagnostic messages to the system log to show you what is happening as the chat program runs. The -t 60 argument simply tells the chat program to wait 60 seconds for the expected text to arrive before timing out with an error.
I would like to know where is the right place to accomplish this. The IP address is the one of your default gateway and the last entry is the device name of your device. Already long time ago, but none of the above described solutions worked for me.
The script is picked up automatically after the pptp connection was created. It works like a charm. Then click on routes and add your route there eg network Your default route for your primary interface? This should be done by default if you're using DHCP. Assuming your interface is eth0 and network is Now if you want a static route that is NOT your default route, that is different.

How do I find out the default gateway for the PPP interface? First of all, you can grab it from the interface info using ip assuming your ppp interface is ppp0 :. Second, when it's ppp, you can always choose "default device routing" over "default gw routing". In this case you could add the ppp0 device as your default device regardless of the gw address, using ip:.

The net-tools way to delete these routes would be to use route del on it. However, net-tools provides no way to differentiate between the rejected route and the other one because the dev argument is optional, though not specifying a device is likely to remove the unreachable route. It might not be unreachable, but prohibit. Use ip route with no arguments to determine which. But, I think you've got something else goofy going on since you have 2 default routes.
