The VPN tunnel comes up and I can start Remote Desktop sessions from the site with the Draytek to the site with the Cisco.
but I cannot do the same thing with the other way - i.e. I cannot open Remote Desktop sessions the other way.
In th cisco log is the following code when I try to connect from the Cisco site to the Dray tek site.
Any ideas what this is and how I can solve the issue?
