Small vent WAN interface control

[TyShawn]

Can someone tell me why after all these years I don't have full control over my WAN interfaces? It really should take support to be able to set my DNS servers on the WAN when the WAN is setup in DHCP, also why is it I can't disable IPV6 on the WAN if I don't want to use it? Just the first ask THIS time has taken me two phones calls and multiple days to get this simple ask.

also why is it I can't disable IPV6 on the WAN if I don't want to use it?

I really feel you...

This I honestly the ONLY router / firewall where I don't have these controls... I don't want to sound like old man fussing, but I don't want to keep calling support and wasting 20-60 minutes a pop for a simple feature I can control on a $70.00 TP-Link...

That’s honestly a pretty common frustration, and it usually comes down to how much control your ISP keeps over their equipment. When your WAN is set to DHCP, many providers lock DNS and IPv6 settings so they can manage the network consistently and reduce support issues on their end. It’s not ideal if you want flexibility, but from their perspective it avoids misconfigurations. If you want full control, the usual workaround is to use your own router behind theirs in bridge mode, assuming they allow it.
