sorry i meant mpd.secret :)

While there even mpd.conf would be useful

AhnHEL

mpd.secret just shows my username and my password displayed on one line in the following format

username "password"

Posted the conf file contents above

Logs look better but still unable to connect while authentication goes through fine. Exact setup on 1.2.3 works as it should.

Could it have something to do with the "label 'startup' not found" error?

Top screenshot is 2.0 logs, below log is 1.2.3.

Give the error of failure during authentication?

AhnHEL

Authentication works, it signs on fine. Just cant connect to anything after that, times out. Same firewall rules in place as in 1.2.3. Thank you for your help by the way. :)

Hmm did you allow gre in/out?

AhnHEL

Firewall rules are setup this way on the PPTP interface

* PPTP clients * * * * none PPTP -> Any

cmb

I saw the same thing doing some testing last night. It connects just fine, but no traffic will pass. All the rules are good, both on WAN for GRE and 1723, and on $pptp. The pptp interface group is correct (for that one connection at least, client is on ng1, PPTP group contains only ng1). tcpdump on ng1 shows no traffic, tcpdump on WAN shows the GRE traffic. Nothing blocked by pf.

After disconnecting and reconnecting, I was able to panic the box. I believe that's related to PPTP, this box wasn't really doing anything else at the time. backtrace attached.

pptp-panic.png_thumb

cmb

After the reboot from the panic, it's functioning (or rather not functioning) differently than I described above. I can ping the client from the firewall, and I can see traffic initiated by the client when tcpdumping on ng1, but none of the traffic from the client gets a response. It's not being blocked by pf, not showing in the firewall log and the deny rules have log on them.

AhnHEL

Any further updates on this issue?

ushac

I have a problem which I am not sure if it is connected to this or not.
I've described it in this thread: http://forum.pfsense.org/index.php/topic,23446.0.html
Is there anyway I can help, with more logs or anything like that?

/Erik

eri--

There is mpd5 now being used for pptp please try new snaps

ushac

Updated using pfSense-Full-Update-2.0-BETA1-20100311-0216.tgz, but no change for me.
Anyway I can help? Logs of some kind?

AhnHEL

Same issue, connecting fine but no traffic passing. :(
