Having recently set up a new SBS 2003 installation with a Draytek Vigor 2800VG, there was some really strange behaviour happening. The client machines were reporting that cookies were not enabled and a Cisco VPN client was connecting intermittently to a Rackspace server. Having gone through all the browser settings, group policy and cookie blocking at the router we could find no rhyme or reason for this. Eventually we found that by adding a WAN IP Alias (which is a way in the Draytek router to add additional static IP addresses and have them added to the NAT Pool) and then configuring Port Forwarding to another Win 2003 Server on the local LAN, that this was causing the error. Take this off and problems went away. I’m leaning towards a bug in the 2.8 version of the Draytek 2800 firmware and have noticed some other people on the Draytek User Forum having strange issues when configuring the port forwarding after upgrading to firmware 2.8. There is a 2.8.1 which is at RC3 so this might be an indication there some issues with 2.8. Also, my own router seems to have Port Forwarding broken and have switched to using the "Open Ports" feature which essentially does the samething after upgrading to 2.8. I’ve submitted this as a support issue to Draytek so we’ll see the official response but I’m just wondering if anyone else has been seeing this?

James Cash has just confirmed to me that he’s been seeing similar issues with Draytek’s running the latest 2.8 firmware. I downloaded and installed the 2.8.1 RC3 firmware and that seems to solve my Port Forwarding issues on my own router. Thanks James.

Glad you got to the bottom of this!
What a strange thing to happen
Hope you get a proper release of the firmware soon!

Yep, it was one of those hair pulling type things trying to work out what was going on! Thanks for your help on it as well.

Similar bug on 2930. If the Router Management Ports are identical, NAT Port forwarding of the same ports on NAT Pool IP does not work. No connection, timeout.
Example:
- Router Managment Port HTTP:8080 on Pool IP 1
- NAT Port forwarding of 8080 on Pool IP 2 to LAN Host xyz: Does not work.
Workaround:
- Change Router Management Port to e.g. 8081
- NAT Port forwarding will work properly.
Also informed Draytek.

Ouch! Surely not another reason to ditch Drayteks and use something that at least works !!!
Another thing to work out for is connecting a Draytek 2600/2800 with site to site VPN with something that knows how to do VPN properly like a Cisco or Checkpoint device - it won’t work or won’t work consistently.
The way which Drayteks send their packets over a VPN stream is not consistent and fails to adhere to RFC standards.. Draytek know about this and don’t appear to care - says it all really!
Save your money and buy a Zyxel for probably even less..
