Draytek VPN Wireless problem...

Hi all,

apologies if this is the wrong place to post! I'm having an issue with a Draytek Vigor 3900 device, it's been working fine as our main VPN for 3 years now (or around that long!)

Recently a lot of our users are reporting that the Draytek VPN isn't working, however after troubleshooting, I seem to have diagnosed the problem...

  • On a wired connection, the VPN runs just fine, no problem at all.
  • On wireless, if using the Draytek Smart VPN Client on SSL connection (our choice of tool), if you have "Use default gateway on remote network" ticked, then the VPN doesn't work at all...

No settings or configurations have changed, it just appears to have completely stopped working.

Disabling the default gateway setting makes the VPN work on wireless (however you then can't access any of our network shares, programs etc)

Anybody ever had anything similar and know what could be causing this?

TL:DR: Draytek VPN has been fine for years, no changes to config, settings or hardware, it's suddenly stopped working for wireless users due to the default gateway..
