Hi,
I'm in the process of moving over from adsl to Telkom LTE uncapped. I have the B315 router from Telkom and my existing router is a Asus N66U.

I want to use my N66U for wifi as the range is better than the Huawei.

What I was planning to do is to DISABLE DHCP on the Asus and use the B593 as the "main" router with the N66U acting as a wireless access point.

However, most of the posts I have seen online suggest doing just the opposite - using the N66U as the main router, disable DHCP on the B315 and connect B315 to the WAN port of the Asus.
(an example: http://mybroadband.co.za/vb/showthr...ion-thread?p=16462533&viewfull=1#post16462533)

My question is - why are the majority of posts suggesting the 2nd way of doing it and not my way? It seems the 2nd way introduces double NAT which can cause issues? There must be something I am missing?

Thanks in advance!
 
A good question. For B593 there is no better option due to the lack of main firewall switch.
It might be a better way for B315s, as you can disable firewall completely. It is expected that disabling firewall on B315s will put router in half-bridge mode, disabling some other routing features. I don't know for sure as in this firmware some features are completely displaced, by example LAN interface IP address and DHCP server options are in WiFi section.
See my first post in this thread: http://mybroadband.co.za/vb/showthread.php/777667-HUAWEI-B315s-LTE-router-discussion-thread

I haven't got application, so I didn't try B315s behaviour yet. Please post your findings, it will certainly interest many people.

What you suggest in the above post, is that when using DMZ there is no double NAT. It is incorrect. It would be confusing for OP who wants to avoid double NAT completely. It is why I suggested investigating option of disabling NAT completely. Such option is not available on B593, it is why you might be not aware of it.

OP here. I do realize that even with DMZ enabled, there is still a double NAT scenario. However, most of the limitations can be sidestepped by using the DMZ. So although not totally optimal, it allows me to still use the better router as a router and the B315 as a "modem"

In such case didn't jcheek give you get proper response to your questions in the above thread? Just follow a guideline and everything will be OK.

You are welcome to continue investigating other option as I highlighted already.

Yes, thanks.
I did disable the firewall. It still will keep the NAT though on the B315, so the DMZ trick looks like the only way to go.
