I want to use an MOTG equipped with a 3G/4G USB modem simply as “WAN selection mechanism” in front of a Mikrotik VPN router. The VPN router would do all the NAT routing for the LAN. The MOTG would simply and transparently pass through to the Mikrotik any of the IP addresses it receives from either Cellular WAN or Wi-fi WAN, depending which one is chosen as priority.
The reason I have to do all this is that the MOTG does not support L2TP/IPSec server/client tunneling capability, which I must have, and the Mikrotik does.
I played with the Peplink Max Interface Demo (I know that’s not necessarily representative of the MOTG). There I could not find any option that would put the whole router into IP passthrough (bridge) mode for all its WANs. I did notice “drop-in mode”, but I’m not clear if that’s equivalent to what I’m looking for and whether it’s supported only on the Balance series or MOTG as well.
My alternative is the $350 CradlePoint IBR600NM, which can be put into what they call IP-passthrough, and which does exactly as I described above. But I would much prefer to use $150 MOTG to perform same.
Would someone enlighten me please…
- Is “drop-in mode” equivalent to full WAN IP-passthrough (bridge) mode?
- Does the MOTG support “drop-in mode” (or some other way, full IP Passthrough on all types of WANs)?
- If the answer to either of these is no, is there a likelihood that the MOTG may soon support what I need?
