We use an old bit of open source kit called Zebedee to allow a small office on a different site to access our accounts software. Had it setup no problems with our old Netgear router, but since i installed a Draytek Vigor 2710n i can't get it configured .

It should just be a case of opening the port that Zebedee uses and forwarding it to the ip that runs the software.. but i can't for the life of me get it working!!

Any help would be GREATLY appreciated.

Nevermind, the problem is solved....

Not sure why it wasn't working, but suddenly it just started working.

ok so it seems that the tunnel will work once or for a while, but then it won't allow any new connections (existing connection is not stopped). Only way i have found to remedy this is to restart the service on the server. But then we are back to square 1 with one remote user able to connect. This has only started happening since i put the 2710n in but i can't figure out whats causing this!!

any ideas?

What protocol / port is it using for the tunnel? If it's using UDP, possibly the DoS Defense (under Firewall, DoS Defense) could be blocking it.

If you set up syslog on the router, that'll show whether the router is actively blocking these connections as it will show that in the firewall log tab.

Thanks.

It is using TCP protocol, but i will try the syslog.
