Hi tik'users.
on a Remote Site we have an RB4011 with v6.48.3 running. This Router has no static public IP, but some remote workers need access to this Network.
In our Datacenter we use CHR as VM (same Version) which is the Dial-in Destination for the Remote Workers and the Remote-Site is Connected via L2TP and IPSEC.
The Dial-in from the Remote's RB4011 (initiator) to the CHR in the Datacenter (Responder) works perfect!
And the OpenVPN Server on the CHR for the remote Workers too!
If the Router on the Remote Site was restarted or disconnected, the L2TP Tunnel and IPsec SA's get up and running, but no traffic could pass until i ping some destinations from the Remote Site to the Datacenter. Is this a known issue and is there an Workaround?
The Problem is, on the Remote Site is no "active" Traffic/Connections to the Datacenter Network, so i had manually login to a device and ping some random IP's from the Datacenter. Then Traffic will be passed in both directions.
Thanks for any kind of hints.
If it's necessary, i could share the configs...
