Device was working great before upgrade to Version 2.1.41.162351.
It would appear that port forwarding configurations are nowing being honored on the internal interface address instead of just the external address.
Router is 192.168.1.1
I have an internal DNS server at 192.168.1.53 with service on UDP 53. I have configured port forwarding for external requests on UDP 53 to be sent to internal 192.168.1.53.
Internal DHCP should be serving DNS server 8.8.8.8, but seeing 192.168.1.1.
DNS requests to 192.168.1.1 are forwarded to 8.8.8.8 without issue and resolve unless you have port forwarding turned on for UDP 53.
It would appear the previous version of the software only forwarded incomming packets on the external interface, this new one forwards incoming packets on the internal interface. So I effectivly get a DNS double hop.
Machine 192.168.1.5 makes DNS request to 192.168.1.1 (As this is what DHCP provided, although configured for 8.8.8.8)
Wireshark shows DNS request being forwarded from 192.168.1.1 to 192.168.1.53, should be forwarded to 8.8.8.8.
My DNS server is now unreachable as I had to turn off the port forwarding in order to get local DNS working without reconfiguring manual DNS server for all my machines.
About to roll back the update .. Anyone else see this issue?
