PPTP/L2TP on interfaces

gnhb · Mar 22, 2011, 12:42 PM

@Loke => There is already a L2TP configuration option in Interfaces(assign)=>PPPs=>Add/Edit PPP page. You don't need to re-invent. :)

Okay guys, I committed some fixes to the GUI code today. There is now a "Connect/Disconnect" button in Status=>Interfaces Page for L2TP links.

Also, you can configure L2TP client from the WAN (or OPTx) pages in the Interfaces menu now (interfaces.php).

I have (I think) working DHCP+L2TP/PPTP code in my repository. (I think only because I don't have an L2TP remote endpoint.)

I followed mickey's lead and forced the L2TP/PPTP link down if the DCHP lease is Released (or any time the DHCP interface is brought down by pfSense.) Is this desired behavior? I assume so.

PM me with your email address and I'll send you new /etc/inc/interfaces.inc and /etc/rc.newwanip files you can put on your box for testing.

If you guys test it out and it's solid I can ask the lead devs if it's okay to add it into 2.0.

Please watch out for what happens when the DHCP lease is renewed. I hope it doesn't kill and reload the L2TP/PPTP link, but please check for that.

If you're savvy with git-sync in pfSense developer shell, the you can git-sync to my repository here:
http://gitweb.pfsense.org/pfsense/gnhb-clone.git

Follow instructions here for git-sync but use this URL above:
http://iserv.nl/files/pfsense/ipv6/

Let me know what happens

The problem we have now is L2TP not connecting on reboot if "local IP" field left empty. Also in /etc/inc/interfaces.inc strings set {$type} self {$localips[$pid]} and set {$type} disable windowing are unnecessary for L2TP and local IP is really not necessary at all.
So i suggest this way:


		if ($type == "pptp") {
			$mpdconf .= << <eod<br>set pptp peer {$gateways[$pid]}
	set pptp disable windowing

EOD;
		}

		if ($type == "l2tp") {
			$mpdconf .= << <eod<br>set l2tp peer {$gateways[$pid]}

EOD;
		}</eod<br></eod<br>

And suggest to remove "Local IP" from configuration page like i did in my version. The only problem is at boot time something apparently needs this single string in config.xml:


<localip>0.0.0.0</localip>

And yes, it can be anything there, even 0.0.0.0

gnhb · Mar 22, 2011, 4:06 PM

To test the code in my repo, set up your DHCP interface (for example on OPT1) and select the "Enable DHCP+" checkbox.

Set up your L2TP interface using the Interfaces(assign) menue => PPPs tab => Add (+) button.
Select OPT1 for your Link Interface on that page. You must select OPT1 if you set up OPT1 as the DCHP+ interface.

Leave Local IP field empty.
Add your ISP's host name in Remote IP field.
Add other info you need and Save.

Then go assign that L2TP link to your WAN interface and Save.

Go to Status => Interfaces and check link status.
Go to Diagnostics => Routes and check that the static route to the DHCP gateway is added and also deleted when the L2TP link comes up and then is down again.

@Loke => Some users may need the Local IP field so it will stay. mpd5 just ignores the windowing command for L2TP. We might take it out in the future.
RE: reboot issue. I have no knowledge of your configuration or your ISP setup. Are you trying to use DCHP+L2TP or just plain L2TP? I can't say anything about your reboot issue. Did you already post your config? I haven't seen it.

eri-- · Mar 22, 2011, 5:38 PM

Loke, than just put 0.0.0.0 at local ip and be done with it.

Loke · Mar 22, 2011, 8:08 PM

@ermal:

Loke, than just put 0.0.0.0 at local ip and be done with it.

Actually i did this :).
gnhb, no matter need you local ip or not it must be field or there will be connect to L2TP server on startup. And i've made the same changes you did with some small diff in interfaces.php and it works the same way.

eri-- · Mar 22, 2011, 8:20 PM

Loke,

if it does not startup at boot you better provide logs.

Loke · Mar 22, 2011, 10:51 PM

@ermal:

Loke,

if it does not startup at boot you better provide logs.

The funny thing is there is no errors related to this in logs. Everything seems to be fine, just it's not even trying to connect when there is no localip in config.xml
And i didn't found any dependence on this string except set {$type} self {$localips[$pid]} in interfaces.inc. But this problem is not related to this for sure.

roi · Mar 23, 2011, 9:55 AM

I am planing to setup a new machine this weekend just for testing this feature.
If there is any thing you'd like me to do-to-it-in-it

eri-- · Mar 23, 2011, 12:16 PM

I just pushed the fix to allow empty localip.

gnhb · Mar 24, 2011, 1:24 AM

I just merged Ermal's changes into my repository and added some minor changes to bringing L2TP/PPTP interfaces up and down manually from Status=>Interfaces page.

Is anyone testing ???
Post feedback!

Thanks,
GB

Hi gnhb,
I sent you a pm asking for those files you mentioned.

thanks.

Ozzik · Mar 24, 2011, 12:04 PM

ok, testing it now. this is what happens:
installed new pfsense 23.3.11 snapshot, cloned gnhb's git and followed his instructions.

regular dhcp on WAN: works as usual (gets the cable network pool IP 172.x.x.x)
checked the dhcp+pptp or dhcp+l2tp on WAN interface, applied.
went to PPPs tab, selected the pptp, the physical WAN interface, typed user/pass, and since I couldn't remember the hostname of the ISP's pptp server - went with the IP. Left the local IP blank. Saved and went back to interface assignment and replaced the physical interface on WAN with the now created pptp. Saved.

It gave me an error at the upper side of the page, but couldn't read it as it was overlayed by the menu(but it did contain the interfaces file in it).
On interfaces status page the WAN connection was down, but had a "connect" button. After pressing that some sort of connection appeared although it was all zeros. On refresh it went back down.

Below are the logs.
In addition to that I decided to relive this experiment, so I changed the WAN back to the regular DHCP, but couldn't get a regular IP, so I rebooted the pfsense. To my surprise it came on asking to define the interfaces on the console(like it was a new setup), but after defining only the WAN it came up remembering the LAN address. Kind of weird.

Anyway, doing this all over again gave me the same results.
Changing PPTP to L2TP did the same.

Any ideas?

@Ozzik => Yes I can see what is happening. You must select "the OPTx" interface and not the physical interface as your "Link Interface" when you set up the PPTP connection.

If you want the DNS lookup to work, you have to have an IP address from the ISP already. I can see in your logs that DHCP starts and then fails/quits/gets killed. I think you have a mis-configuration in your setup. Read my instructions again and see it what you did really matches what I described.

Ozzik · Mar 24, 2011, 1:35 PM

ok, I did what you suggested.
This brings me to the "fatal trap 12" every time I press connect.
the messages in the log look the same (regarding the routes), but the error I get on the console is this:

stopped at ng_ether_atach+0xdf mol %eax,0x4(%edx)

plus, when I reboot it from there it always comes up fixing some file system errors.

Can you figure out why your DCHP client is bailing out?

Ozzik,
See this thread about DHCP client issues: http://forum.pfsense.org/index.php/topic,34791.0.html

Once that is worked out you might not have any problem with the PPTP/L2TP link.

After two days this is what I came up with:

Intel P4 2.6Ghz
Asus P4P800-ES Mainboard
3Gb DDR 400 Ram
Nvidia FX5200
Nic's:
1. On board: Marvell Yukon 8001
2. 3Com Etherlink XL 3c905b
3. Compaq NC3120 (Intel 82557 chipset)
4. Realtek 8139D
5. Davicom 9102
Running : pfSense-2.0-RC1-i386-20110325-1028

At the moment the Marvel is set to be WAN and is connected to a ADSL router feeding from another ISP.
One of the Nic's will be connected directly to the Cable modem.
Third will be LAN to a control desktop.

Let the games begine…

Hi,
sorry I couldn't do this earlier. But now I have some testing pc, so I can do this more comfortably.
Regarding the dhcp. When I set the WAN to just DHCP - it works. No problem, I get the right IP (172.x.x.x).
Only when I set it to "DHCP+" it starts to get flaky.
this is the first part of the log, it's right after the reboot (after I reassigned the interfaces through the console, WAN is on DHCP now):

as you can see - the DHCP worked.
now I check the DHCP+ option, apply, go to PPPs and create new pptp config(attach it to WAN, not physical interface). Then I assign the whole thing to WAN on the main "assign interfaces" menu, instead of the physical one.
this is the log so far:

In addition, this is the error I get (overlayed by the main menu):
warning: invalid argument supplied for foreach() in /etc/inc/interfaces.inc on line 3089

Now I press "connect" button on the "interfaces_status" page:

php: /status_interfaces.php: wan: pptp link configuration failed. No ip address found for gch.bezeqint.net.

Jan 1 00:30:54

that's that, nothing happens.
this is my config - pretty much all defaults. I opened the firewall rules wide open just for the sake of the test.
