Hello
I followed the tutorial sto make a PPTP server using optware (poptop)

I believe everything's fine except one thing.

I am using PPPoE to connect to internet.
The poptop guide clearly says that i have to create a .wanup file so the chap secrets will be moved into the tmp folder

#!/bin/sh
if [ ! -f /tmp/ppp/chap-secrets ]; then
   mkdir -p /tmp/ppp
   ln -s /opt/etc/ppp/chap-secrets /tmp/ppp
fi
/opt/etc/init.d/S20poptop restart

well, the file exists and it has my credentials for my PPPoE connection to ISP.
So I get error than username/password is wrong on clients.

What can I do to sort it out?

Basically i found out that even if I put some username and password manually it will break the current PPPoE connection thus the connection to internet?

How can I solve this problem?
