17.1 Legacy Series / 17.1.5 no DNS access for VLANs
« on: April 26, 2017, 11:48:14 am »
After the upgrade to 17.1.5, name resolution doesn't work for VLAN members.
Using the tools from the GUI, everything works fine.
The firewall is not blocking the outgoing requests, but it seems the answers never make it back.
VLAN define their own (external) nameservers
VLAN uses OpenVPN link as a gateway.
Nothing special in the logs.
All gateways and services up.
No proxy, no IDS.
What's the best way to debug this?
