What you need to achieve what you want is a Dual-WAN router, or better yet an xDSLDual-WAN modemrouter combo.By design, if you supply one of these routers with: an active 4G SIM connection, and a working internet connection via the eth4 LANWAN port, with the eth4 connection mode set to Dynamic IP, the router will always prefer the ethernet connection via eth4.It will only flip over to packet data via the 4G SIM connection if you remove the cable from the eth4 WAN port.
We have an application where we want the B315s router to do the reverse. Is there any higher level admin login that allows us to set the connection priority for different types Or an alternate firmware with slightly different featureset (needs to still work with VF RBI SIMS plans). It seems likely Im not the only person to have ever wanted to do this in NZ, let alone the rest of the world, but my Google-fu fails me. The B315 WANLAN port was set to LAN only with all traffic set to use the 4G connection as primary. All non critical clients were simply set with the ADSL modem as the default gateway (as were all other clients in a backup situation) Your other option is to get a proper Dual-WAN router and connect the B315 and your ADSL modem to that and let it do all the connectionfailover work. That could work if it was only a couple devices, but this particular site is a remote office where roaming users will connect on ad hoc basis ie frequent client device changes. I have found the failover method from eth - 4G to be relatively effective in testing, but as you say its not really a proper dual-WAN router. Got any good device recommendations then, where I can set the default desired Primary connection Ideally, it would be one that has its own internal SIM slot, rather than using those flaky USB modems that end users can knock out or try to swipe for their own use.

I was starting testing with the B315, since it is what VF supplies, and they are our company ISP. You just need to be aware you cant use a Spark, Skinny or VF FWA SIM card in 3rd party hardware. I can only find NZ-based list pricing for the older -E and -A2 variants, which seem to be 3G-only, so I can only imagine what the -M pricing is like for newer 4G variant. Please pardon my ignorance, I dont know what the FWA acronym stands for, or what the implications are. Please pardon my ignorance, I dont know what the FWA acronym stands for, or what the implications are FWA - Fixed Wireless Access All it means is that all providers lock the SIM card for their FWA products to the router it came with (all in NZ are the Huawei B315 variants now if Im not mistaken) so you cant just take the SIM out and use it in an alternate 4G3G router, it just wont work. In your original post you indicated you were using Vodafone RBI so to use that youre stuck with the Huawei B315s-307 for your 4G access. Something like this: You then connect your xDSL line to the Asus DSL port as one WAN and connect from a LAN port on the Huawei B315 to the Asus WAN port as the second WAN. Then you can go into the Asus configuration to setup the Dual-WAN failover as you want, eg 4G as Primary connection, ADSL as Secodary connection. Youll end up with double NAT on the 4G connection but since all 3G4G connections are CG-NAT anyway this shouldnt be a problem. Also turn off Wi-Fi on the Huawei so all connections run through (and are therefore managed by) the Asus. Youll also need to make sure the Huawei LAN is using a different IP range to the Asus LAN as the Asus cant have the same IP range on both LAN port and WAN port).
