Hi Xiaofan,
Apologies for replying back to this.
I was trying to complain back to Singtel on the lack of customability for customers who wish to configure to their own settings. Overall i was denied any form of cancellation and had to incure a $3000 penalty fee. Moving forward it seems like the officer handling the case was not able to help me which is just a luck basis. Therefore i retained the 10gbps contract as it is. To those who have better luck handling with the officer i wish you all the best ahahhaha.
Anywho, I have ditched the setup of using Asus ROG GT-BE98 instead. I was in the Singapore FB Ubiquiti group and someone sold me a UDM Pro for only $200 in full working condition.
My initital test was to see if i can configure to the settings i want without losing any IP address that i have set. And turns out all is according to plan. The double NAT situation doesn't affect me, i just need my stuff not to change IP all the time as i access my servers often with quick access from mapping the network drive.
The unfortunate part is that the HB810 routers are still very finicky and does not really give me the wifi7 that i desire. The connections is also pretty unstable [already changed to APs with the second on a mesh]. But overall i cannot tweak any of the settings from HB810 and every slight change the APs seems to go nuts.
Despite the above, i choose to retain back this setup because since my UDM dream was fulfilled, i immediately ordered the rest of the other components i need for my planned setup as of below:
ONR > UDM PRO
UDM PRO
> Unify 8 Port Aggregation Switch [10gbps SFP]
> NAS 1 [Only 1gbps]
> Printer
Unify 8 Port Aggregation Switch
> Unify pro max 16 POE
>>1x G5 Flex POE camera
>>2.5.Gbps to work laptop [through belkin multimedia hub]
>> PS5
>> Nintendo Switch
> FLEX XG
>> Second PC [Only 1gbps]
> Main PC
> NAS 2 [10gbps capable]
> HB810 [Main] >> to all Wifi Devices
I have seen online that U7 pro max has received plenty of bad feedback due to instability issues and there might be a chance a better version will come out. Thus I am willing to wait for that [An excuse because i have spent a ton on the other required equipment hahahaa].
Overall, i am very happy with the interface from Ubiquiti, i do have friends who recommended Omada instead. I do admit that while Omada hardware is very strong, and the overall cost from my above setup is definitely lower [provided i bought the udm at full price], however, the interface on the Omada really doesn't work for me. Thus i can say i went to the "dark side" on the Ubiquiti chain.
Attached a photo to show my "the interlace" junk setup without any racks hahaha
