I have set up a test environment in to create a very simple setup to establish a layer-2 bridge via a PepLink VPN between two UBR-LTE wired WAN ports. The setup looks like this:
PC1 ---- UBR-LTE (wan)---------------- (wan) UBR-LTE ---- PC2.
where the wan ports have hard-coded IP addresses (10.10.10.1/24 and 10.10.10.2/24).
The PePLink VPN is established between the the two devices and Layer-2 bridged to the LANs of either device to extend the network from PC1 to PC2. Simple enough.
But I am seeing it take in excess of 2 minutes for the PepVPN to be established and start passing traffic after a disconnect and reconnect of the WAN-to-WAN Ethernet cable. [Actually once the link is established, a if I unplug the WAN-to-WAN Ethernet cable for < 10 sec, the system passes data almost immediately when plugged back in. If I unplug the same cable for > 30 sec, it takes more than 2 minutes to re-establish the connection and pass data.]
Are there configuration strategies that can improve this horrible setup time?
I need to be able to remove the WAN-to-WAN link for extended periods (10’s of minutes or more) and have the PepVPN pass data almost immediately when the connection is re-made.
