We currently have a number of RB450s creating a VPN network for some road warriors back to another Mikrotik device acting as the VPN concentrator. I would like to get a second internet connection for VPN concentrator, but I don’t know how I would configure the clients to try a second server IP if the first one fails. Could anyone let me know if this is possible and how I might accomplish it. TIA
I assume clients are connecting to a FQDN, i.e. myvpnserver.mydomain.com; you can set an external DNS so that it resolves to both WAN connection addresses, or so that it fails over to the backup connection in the event of the primary one failing.
