Hello. I just installed OpenWrt on two Linksys EA7300V2 routers. One is plugged into my ISP router/modem, and the second one is connected to the first Linksys LAN<->LAN. I enabled Fast Roaming on both of them and the second router is set to 'DHCP Client' mode. I did this all by following this guy's instructions: https://www.youtube.com/watch?v=kMgs2XFClaM
Now, I am extremely happy with my setup, getting about ~93% download speeds of my internet package, but I have one weird question. So far I've installed and configured some extra stuff on my first Linksys router (the one connected to the ISP router/modem). I enabled DoT, software+hardware offloading, etc. The results are great, but I'm wondering, do I have to do the same things on the second router as well? If not, why not? I'm especially wondering about the hardware+software offloading because enabling them gave me a huge boost in download speeds.
I'm very new to this and appreciate all the help. Please tell me if there's some crucial info about my setup that I missed to mention.
Also, on a separate note, I would be grateful if someone could tell me how to disable IPv6 and all related services.
On "the first router" doing DHCP.
Network/Interfaces/DHCP server/IPv6 Settings:
Disable all.
Save and apply.
Reboot.
You should not see any DHCP leases in the Status home page.
You will still come across IPv6 settings here and there. Only disable something that has an option to enable; do not change any numerical settings.
The only thing I can disable there is "Local IPv6 DNS server". Is that enough?
Network/Interfaces/LAN-edit/DHCP server/IPv6 Settings:
Disable all.
Sorry about that.
No worries, I figured as much but still, Local IPv6 DNS server is the only setting I can disable there:
RA-Service
- disabled
▾
Configures the operation mode of the RA service on this interface.
DHCPv6-Service
- disabled
▾
Configures the operation mode of the DHCPv6 service on this interface.
NDP-Proxy
- disabled
▾
Configures the operation mode of the NDP proxy service on this interface.
Ohhh, that makes much more sense, thank you. One related question: I set up DoT by following this guide. Now that I disabled RA-Service, should I omit these line from the /etc/config/dhcp?
config dhcp 'lan'
option dhcpv4 'server'
option dhcpv6 'server'
option interface 'lan'
option leasetime '12h'
option ra 'server'
option ra_management '1'
Save, apply and reboot.
One would hope LuCI would do that.
I do not know how to CLI IPv6; I just know how to kill it in LuCI
Thank you, much appreciated!
