Client VPN connection of the router not established when Internet WAN is the SFP+ port
Hi to all,
my client VPN connection established from the router stopped to work when i move my Internet WAN connection from the 10G Ethernet interface to the SFP+ interface.
I used the client VPN feature (OpenVPN) specifically on one LAN connection, for using a TV box with an italian service that has IP geographical limitation.
I recently moved to a full fiber operator. I activate the connection with their router and the Archer connected in cascade (same as for the previous provider that was a cable one): all worked fine, Internet and VPN ok and i tested for few days, all OK.
Then, I decided to connect directly my Archer to the fiber, with a SFP+ ONT on the SFP+ interface.
I discussed with my internet operator, done what was necessary and I got Internet connection working fine: unfortunately, i noticed that the Archer VPN connection is not established (on the Archer web interface remains "connecting" for ever). No error messages also on system log.
If i try to use the VPN client application on the PC or directly the app on the TV box, the VPN is established.
So, only the VPN connection of the Archer is not working.
It's not an issue of VPN configuration parameters on the Archer, since they were the same when using previous Internet provider and current provider when using 10G WAN interface.
The SFP+ ONT should not be the cause since i have Internet connection and VPN connection if i started from PC or app.
Also no filtering from Internet provider for same reasons.
It's like the Archer is not routing the VPN request to the SFP+ WAN interface.
Anybody experience such issue ?
