Hi,
I have a problem with WL-520GU a PPtP connection.
I get errors:
Jan 1 01:00:09 dhcp client: deconfig: lease is lost
Jan 1 01:00:11 dhcp client: bound IP : 10.71.0.192 from 10.71.0.1

Jan 1 01:00:29 pppd[83]: Modem hangup
Jan 1 01:00:29 pppd[83]: Connection terminated.

my settings in windows pptp are extended:
encryption: none or optional
on unencrypted password (PAP)
off shiva-password-authentication(SPAP)
on Challebge-authentication-rotocol(CHAP)

what to I have to change in the WAN & LAN settings of the router?
I already tried PPtP Options: No ENcrtpytion but it didn't helped.
rest off
