Poptop installation

[Jethro]

I have installed the poptop package with ipkg. I have gone through the pptdp.conf and options.pptpd files and verified that the service S20poptop is running. The problem I am having is that I can't connect from LAN (not tried WAN, needs iptables config first).

I have altered the pptpd.conf file to match the following:

localip 192.168.1.1 (=my router's internal address)
remoteip 192.168.1.100-110, (=the ip's I want it to use)

Not working when trying to connect from a LAN client to the router.

What other configuration steps do I need to perform?

[pfugl]

Jethro, did you ever manage to get this working?
If yes could you give me the steps?
If not - anyone else has it working?
I am running into authentication errors, though I have made the chap-secrets file correctly and placed it in:
/opt/etc/ppp/chap-secrets
(perhaps this is the wrong place?)

Hi Pfugl,

it takes a few hours for me but finally I found the right place for the file.
It is in the /tmp/ppp directory.
I did a little workaround and place a symlink from my original file placed in /opt/etc/ppp
at boottime with the post-boot script into the /tmp/ppp directory.

Not working when trying to connect from a LAN client to the router.
Uhmm, Jethro, is this subnet you use for the tunnel (obviously something
like 192.168.1.0/24) the same as your LAN-subnet? As you state, your
routers internal address, which is part of the LAN-subnet, is also in the
subnet you want to use for your tunnel-client. So I guess the answer is yes.
And I think the pptp-protocol was not designed with that option in mind.
If you really insist on testing it on your LAN first (which is by all means a
good thing in my opinion) then you better introduce a separate subnet.
I believe your LAN-adapter can become part of that new subnet simply
by adding an IP-alias to it:

ifconfig br0:0 192.168.3.1
It will be default get a subnetmask of 255.255.255.0, but if you want to
overrule that you can use:

ifconfig br0:0 192.168.3.1 netmask 255.255.0.0

And you can delete the alias by:

ifconfig br0:0 0.0.0.0
It will complain:

SIOCSIFFLAGS: Cannot assign requested address
but the alias will vanish.

Maybe that helps...

Good luck, and regards, Jaap.

Thx MMX.
It would be very nice if some could do a how-to for this. Every little step forward creates new problems. Well - that's life I guess. After creation of the new chap-secrets file my log looks as follows when I connect from XP from the lan side:

Hi Pfugl,

it seems you have a problem with GRE or a mistake in your configuration file.

Thanks mmX.
In the meantime I found out that in fact I could connect 1 time out of 4 from winXP client.
I have now changed my config files to match yours exactly, (except user/password), but still only succes in 1 out of 4.

Another strange thing is that my default route inside the router disappears when the client is connected, so i cannot connect to my ISP anymore.
When I have a succesfull connection my log looks as follows:

As you can see, the difference is that the SET LINK INFO packet is never received. An Etherreal trace from the client confirms that it is never sent from XP in the failing situation.

The route problem shows up if I try to do a ROUTE command inside the WL500 - it shows the first 4 routes and then hangs (the # prompt does not return, but it can be terminated by a ctl c). The default route does not show up. Perhaps the wl500 only allows 4 static routes?

I should add that I am connecting from the LAN side - I have not had any succes from the WAN side yet.

[mmX]

Hi Pfugl,

I have got exactly the same problem that WinXP-clients connect 1 time out of 4.

http://wl500g.info/showthread.php?t=1771&page=3

But I also don't know how to fix it. :(

I set up 6 route entrys and if I type the route command it takes a little while,
but I see all my route entrys.

If you want your poptop-server is reachable from WAN side you must add the following rules
to your post-firewall script:



iptables -A INPUT -p 47 -j ACCEPT
iptables -A INPUT -p tcp --syn --dport 1723 -j ACCEPT

What environment to you have?
I've got a Wl500g running with Olegs 1.9.2.7-6b firmware.
Maybe this might explain the different behaviour of the router.


Best regards

mmX

[pfugl]

Hi mmX.
I have given up to make this work reliably. I have a WL500GX with Oleg's 1.9.2.7-6b fw.
Something is going wrong in the kernel I think. When connected, the Route command and the IPTABLES command both hangs halfway through. When I disconnect, both of the commands will resume the hang and continue their operation to the end.
Also I have added the iptable entries you describe, but when I connect through wan, it hangs on userid/pw authentication.
/Peter.

[hugo]

Ok, back to the subject because having a PPTP solution on wl series is an important point if you use pocket pc for example.

The 4 times to connect bug is also on the pocket pc client. This is a server problem, because if you hang the connection too early on the PC side, it will not count in the "4 to go" to connect. I guess we have to get a newer version for this one.

About the connection problem: the issue is that the routing table shift when the ppp0 link is established. As you describe, it is very long to get the routing table. The router also lose connectivity with WAN when the connection is established, on laterst Oleg firmware. Using the web interface, in the status page, you can see the router believe that the WAN interface is now the ppp connection. When hanging up, the router can ping again, but the client get usually a mangled routing table, with metric going up to 20 or 30, which is a result of a bad routing configuration (client get this if your router doesn't answer). You usually have to restart to correct this, or you have to do it by hand.

So the question is: how can we set the WAN interface. I guess this is the default route in the routing table, but if it is so, can we correct this table during the ppp link? The firewall is just a secondary problem, because if the ppp link becomes WAN, it is of course blocked by the firewall. If you open it, all packet goes through between client and server.

Another remark is that we might need another version of pppd, as it is probably the one creating the problem. What do you think?

Hi BadDude,

just disable logwtmp in the pptpd.conf.
Its only for logging the client connection, but in the syslog you
also find who logged in.
