Comment on Chaining routers and GUA IPv6 addresses
maxwellfire@lemmy.world 2 weeks agoI’d recommend something that you can put openwrt or opnsense/pfsense on. I think the tplink archers support openwrt at least.
The ISP router opening things at a port level instead of a host level is kinda insane. Do they only support port forwarding? Or when you open a port range can you actually send packets from the WAN to any LAN address at that port.
Can you just buy your own modem, and then also use your own router? (If the reason you need the ISP router is that it also acts as a modem).
Does the ISP router also provide your WiFi? If it does you should definitely go with a second router/access point and then disable the one on the ISP router.

And openwrt is capable enough?
Yeah it’s insane right? Every address is reachable when I open a port range. And it’s like there are ~ 10 predefined services (HTTP/S, SMTP, …) and the category “All other ports” where also 22 is part of. So I really have the choice to either keep everything shut or leave everything wide open.
I think I can’t use my own modem but I’ll have to double check with my ISP. But yes the Wi-Fi is also provided by that router and it’s also quite crappy.

Yeah openwrt should be great. It uses nftables as a firewall on a Linux distribution. You can configure it through a pretty nice ui, but you also have ssh access to configure everything directly if you want.
The challenge is going to be what the ISP router supports. If it supports bridge mode then things are easy. You just put your router downstream of it and pretend like it’s a modem. Then you configure openwrt like it’s the only router in the network.
If you don’t have bridge mode then things are harder. There’s some helpful information here forum.openwrt.org/t/…/19 even though the situation is slightly different since they also don’t want a firewall. But you probably need to configure your upstream side on the openwrt router similarly.

That’s really helpful, thank you. I’ve ordered an AX23 which will arrive tomorrow. I’ll try to figure it out in the next few days and report back.
