Max number of open NAT connections on GT-AXE16000 and GT-BE98

[Jean42]

I currently have a GT-AXE11000 and the max number of open NAT connections (cf Tools page) is 300000 which might become a limitation for me and I was wondering if the GT-AXE16000 or GT-BE98 had a higher threshold in which case I might upgrade.

Can you not already change that on Tools - Other Settings?

What would be the purpose of limiting or reducing the max # of NAT connections?
This setting is only in Merlin?

I'm highly in doubt any home router can actually handle 300K connections.

Probably very little purpose. In rare circumstances you might want to increase the limit as per the OP's request.

This setting is only in Merlin?

Yes, the Tools page is only in Merlin's firmware.

Interesting, I didn't see this one, only problem is, 300000 is the max value accepted:

The only way to reach this high number of connections with your limited number of clients is heavy torrenting and the router will slow down to a crawl long before that. Leave this value at default and don't worry about it. You are trying to fix non-existing at the moment problem.

You could override it by editing the nvram variable directly from the command line. But I'd suggest you leave it as it is until it actually becomes a problem. 300,000 is already very high.

No torrents, but clearly not something that the average user will do (hosting nodes for some blockchains).

I'm currently at ~100K open connections, router CPU ~30% usage, no noticeable impact on RAM. No impact on bandwidth and latency. I'll see how it goes when I reach 300K, but if the cpu is a limiting factor, switching to GT-AXE16000 or GT-BE98 won't solve it since it's the same cpu but with a slightly higher frequency.

This is not what home routers are made for. If you have special requirements you have to find appropriate hardware.
