Topic: VPN Does it work or not. Will anybody fix it?

[Medimo]

For me PPTP worked out of the box, using 5.5, 5.6 and 6.0 using all kinds of windows clients.

The only thing is that sometimes the VPN-connection is broken and new connections are refused for a certain amount of time.

grz,

Richard.

Below is a snippet of the log file. I can no longer connect o this SME box with SME 603beta. It worked fine before. Any help would be appreciated. The error on the client side is 619. I get as far as the login session, then it errors out to error 619...Jonnybb1

felipevida

All my Errors are gone.

[Anonymous]

I have setup VPN on both 6.03b and 6.0.01 custonm vpn services using DSL @ both ends and have not had a bit of trouble !!!!!


Maybe its a PEBCAC Error......
Possible error between computer and chair!!!!


digout the dummy's BOOKS!!!!!

[Mark R]

I have the same problem with VPN... i've set everything i believe i should set...

1 set account to VPN
2 forwarded port 1723 on router to SME
3 forwarded port 1723 on router to the client

and still no joy....

maybe PEBCAC error.... but who knows

[PhilV]

and....

4) Enabled Max PPTP connections to be a number greater than 0

????

Easy to forget that one!

Phil

[Mark R]

Yep.... done that one....

[MSmith]

If you can do that, the SME box's external interface will be directly exposed to the Internet (as is intended, and provided for) and you won't have to worry about forwarding any ports.  Your router might also have a "DMZ" setting, as it's called in some Linksys routers, that also directly exposes a certain IP address to the Internet.

[harro]

Plus:

5) nat create protocol=47 inside_addr=10.0.0.xxx outside_addr=0

?

[mbachmann]

Your router might also have a "DMZ" setting, as it's called in some Linksys routers, that also directly exposes a certain IP address to the Internet.

Just as a remark for nitpickers like me: What most routers are calling DMZ ist NOT DMZ. It is called what you've mentioned: exposed host.

[Mark R]

Aaaaarrrrgggghhhh still not working..

tried everything and still no luck

Saw that this morning. I've said it before....for all you want to talk about United and their international profile http://download-games.b0x.com/, they really seem to do business the right way. I'm interested to see just how much Kenyon had to do with these results, so next year will be interesting.

See the message below. It is about the post above this one

DO NOT click on the above link. My Avast antivirus software caught it as a virus

Try this for a quick workaround:

/etc/rc.d/init.d/masq restart

I had something similar with 6.0.1-01. All over sudden it started working again after restarting Masq.
