Hi,

I'm not sure this has been tackled before... I searched the forum but cant seem to find much...

I have an RB500 natting my internal network.
I can connect to a PPTP server on the internet, from one of the internal PC's (through windows VPN connection).
Till now all works fine, and this means that firewall rules for GRE etc seem to be set up well.
However if I try connecting another client on the same subnet to the same PPTP server, I get error 619 after verifying user/pass.
If I disconnect the original client and leave some time, I can now connect from the second PC.

Any hints?

Thanks!!

in /ip firewall service-port

Hello. I have the same problem with pptp. In firewall-service-port i see GRE and PPTP enabled,but in these lines not specified any port number. What valyes i need write in these lines?

ports for gre and pptp are not needed, they should stay empty
