I have the following setup as described in this link.

http://wiki.mikrotik.com/wiki/SSTP#Application_Examples

Under connecting remote client example.

I am able to ping other devices and the local interface on the RB433 but, I cannot use winbox to connect to the remote RB433 thru the vpn. I get the following error when trying to connect winbox using the internal LAN IP address over the VPN.

could not get index: fatal error!

I can connect the external public ip address over the VPN though.

As I said before, I can ping all local interfaces on the RB433 but, can't use winbox to connect. I tried adding routes toe the PPP secret, but this did not work either. No firewall rules preventing local users from accessing routerboard thru winbox. Any help would be appreciated. Thanks again.
