PPTP/L2TP on interfaces
-
Okay. I get it now. I looked up with Google!
You have a cable modem right?with HOT right?

that's right:)
was i right in my assumptions?

Hi,
Thank you for working on this option.
I tried to test it by setting the physical interface as opt1 (dhcp ) and assigning the l2tp to wan.
Tried also by directly setting wan as l2tp and in the mlppp tab setting its physical interface. But i don't see it trying to connect (nothing in the system log and ppp log + wan is down).Am i doing something wrong here ?
Is there a way to see a more verbose log of the pptp/l2tp connection ?Thanks !

Some code that does this is currently in snapshots from June 15th or later, but it's commented out. You must uncomment it in /etc/inc/interfaces.inc like this (code below), and you must have a separate interface defined (like OPT1) that is set to enable DHCP on the same physical interface that the PPtP link is using.
The PPtP link won't come up at boot time. You'll have to start it manually from Status->Interfaces page. This will hopefully be less manual in the future.GB

Hi,
finally got around to test it.In my testing environment I only have WAN and Wi-Fi for LAN, so I set WAN to DHCP, created another interface (OPT1) on the PPPs tab and configured it to PPTP. I also uncommented the code you mentioned, but as Micky said previously - nothing happens.
I see the "connect" button on the "interfaces" status, and when pressed - nothing happens, no logged events, nothing.
Am I doing something wrong?

I've managed to get the PPTP to dial up, but the no traffic outside.
I think the problem is the gateway, in the gateway list i can only see the DHCP gateway thorough which i dialed the VPN and not the PPTPs.And in PPP log:
Aug 3 20:07:29 ppp: [wan] IFACE: Up event

OPT1 as DHCP (on physical interface)
WAN as PPTP (on OPT1) – and not on the physical interfaceOn L2TP it somehow tried to dial once but i cant repeat that, there is no button to start the interface in the status_interface.php page,
just "Status down".Edit:
Probably NOT the gateway, if i try to ping something the host name is resolved correctly. -
Try allowing traffic to flow in the firewall rules.
-
Micky,
can you be a bit more specific about how you set up the interfaces?
Did you enable the OPT1? What did enter on WAN interface in the regular "interfaces" page?
What/where did you enter on the new PPPs "interfaces" page?Thanks.

Starting with WAN set as DHCP on fxp0
(my wan physical interface is fxp0.)I did the following:
1. added PPTP link in ppps tab on fxp0 (will be changed later)
2. added OPT1 interface in the assign tab.
3. swapped OPT1 to fxp0 and WAN to pptp (assign tab)
4. went to the OPT1 config page, enabled it and set it do DHCP
5. in ppps tab edited the PPTP link and changed it from fxp0 to OPT1 (without this nothing will work)I didn't touch the WAN config page, it is automatically set to PPTP with the username and password.
And i'm dialing the PPTP server by IP ( i dont know the pptp hostname, only the l2tp [my isp: 014])I can ping the gateway and the hostnames are resolved correctly but no more then that.
Already tried to add Allow rules (any protocol) on all interfaces.
The weird part if i trace route something the first ip is 10.xxx.xxx.xxx (trace & ping done from console)
and i shouldn't have anything of this type (my lan is 192.168.xxx.xxx, OPT1 is 172.28.xxx.xxx and WAN (pptp) is 84.xxx.xxx.xxx).I'll try clean install and L2TP after the file edit bug fixed as VI and I are incompatible. :-\
(oh, and don't restart, the pptp wont connect after restart)

And here the l2tp log:

Managed to get L2TP working, modified interfaces.inc a bit, and still a small problem with DNS, gateway and that the L2TP interface doesnt have connect/disconnect button, but i'm writing this through pfsense.
changed:
if ($type == "pptp" || $type == "l2tp") { $mpdconf .= << <eod<br>set pptp self {$localips[$pid]} set pptp peer {$gateways[$pid]} set pptp disable windowing EOD;</eod<br>To
if ($type == "pptp") { $mpdconf .= << <eod<br>set pptp self {$localips[$pid]} set pptp peer {$gateways[$pid]} set pptp disable windowing EOD; } if ($type == "l2tp") { $mpdconf .= << <eod<br>set l2tp self {$localips[$pid]} set l2tp peer {$gateways[$pid]} set l2tp disable windowing EOD; }</eod<br></eod<br>(and uncommented the gateway part)
And after the link is up had to change the gateways, In pfsense console i did
route delete default
route add default 212.xxx.xxx.xxx(where the 212.xxx… address is the gateway acquired via the l2tp vpn dhcp - it is added to the table but not as the default route)
-
I have triad to do the same (Also 014 as ISP) but no joy.
Triad both l2tp & pptp.but just to be sure -
When I create the l2tp interface, I put the 212.179….. in the Gateway and leave the Local IP blank.
Am I correct ? -
Yes,
Where you got with it, dialed but no connection? nothing dialed ?
Notice that you must switch the vpn connection base interface to opt1 or it wont dial at all.
(enable & set opt1 to dhcp before that)And for L2TP I tested with the host name (hot.bezeqint.net = 212.25.127.14), for PPTP server I tried with the ip addresss
(212.179.61.76 - i dont know the host name)Also if you restart the box you'll have interface mismatch and you'll have to start everything from scratch.

What I am getting is: ~
Aug 6 08:01:36 ppp: [wan_link0] Link: reconnection attempt 8013 in 2 seconds Aug 6 08:01:38 ppp: [wan_link0] Link: reconnection attempt 8013 Aug 6 08:01:38 ppp: [wan_link0] PPTP call failed Aug 6 08:01:38 ppp: [wan_link0] Link: DOWN event Aug 6 08:01:38 ppp: [wan_link0] LCP: Down event Aug 6 08:01:38 ppp: [wan_link0] Link: reconnection attempt 8014 in 2 secondsand my virtual port is opt4.
I used 212.179.61.78 as the server for both L2TP and PPTP, as far as I know all 014's servers support both, so we might be able to connect using hot.bezeqint.net for both ppp's.Also - I think that I have a bug of some sort. the machine is trying to connect using L2TP and in the "Interfaces: Assign network ports" page I can assign l2tp0 to the port's but I don't have it on the "Interfaces: PPPs" page to work with.
seem to be a leftover from the test's… -
Never tried l2tp on 212.179 but i tried pptp on hot.bezeqint.net and it wont connect in windows,
so i think they use different servers ( i was surprised too as 013 use the same address )And what you describe happened to me several times, mainly if i restart one of the connection (or the entire box) or the opt interface is not enabled.
-
Until the moment where you are actualy connected to your ISP (014 in our case) and recives your static IP address from them, you are in the domain of HOT. They have the server that "sends" you to the ISP. SO hot's server can do it for all ISP's.
As far as I understand.
-
Where can I find the settings for pptp/l2tp links after I save them ?
I got a feeling that I have a ghost in my machine.My ppp logs show that the router is allways trying to dial out, but the ppp interface tab don't show that any link exist.

Show the section of patched code here, and the file /var/etc/mpd_wan.conf (or /var/etc/mpd_opt1.conf) and the output of these commands from the command line. (Uses page Diagnostics -> Command Prompt if you don't have terminal access).
ifconfig
ps auxw | grep mpd5
Also, show me the <ppps>section of /conf/config.xml

Hi, should i post it, or you were talking about Roi's configuration ?
And i don't know if this is the problem:
http://redmine.pfsense.org/issues/813But if L2TP set, after restart there is "interface mismatch" error and all the configuration lost.
Also is it possible to set the VPN to overwrite the DNSs ?
(to overwrite the 2 DNSs received from OPT1 DHCP)Thanks again for doing this options !!

Everybody should post the data I asked for.
