Hi Sifus, as per title, looking for 5G or 4G unlimited WAN backup with no proxy/no-NAT.

reason: sometimes fibre service outage. need web services to be always available.

current setup: dual-wan biz router with failover via rj45 or USB port.

searched the forums, but so many threads couldn't find direct answer.

thanks in advance!

All telco (wireless broadband) are providing only private IP, i don't hear local telco provide public IP (while in HK some does).

so there is NAT if you are connecting using 4G/5G

you can try wireless but not 5g/4g

Thanks for the quick replies.

It'd be nice if optional addons exist for public ip features.

Pm me

I don't think any of the mobile internet providers here provide those plans, at least publicly

I suppose you should try contacting their business department
