Hello everyone,
last year I bought a MC PMRL router to run a pptp server on it.
pptp is necessary because the Remotesoftware works with it .
To make the pptp connection safe I put the pptp connection in a openvpn connection.

Now I have a problem to run the pptp server on openwrt I cant finde the 'pptpd' package witch is necessary to adjust the server.

root@MC-PMRx:~# opkg install pptpd
Unknown package 'pptpd'.
Collected errors:
 * opkg_install_cmd: Cannot install package pptpd.

wiki.openwrt.org/doc/howto/vpn.server.pptpd

I hope someone can help me smile

I have done that, of course. But I don´t can find the package.

How about you try this command

opkg list | grep pptp

I was able to install all packages manually, if i want to build the connection remotely, the log will give me the following logfile.

Maybe someone can help me with this:

Looks like you need to install the MPPE kernel module.

I guess I need the following package: kmod-mppe ?

The discussion might have continued from here.
