Plethora of questions regarding running OpenWRT on Pi 5

Installing and Using OpenWrt
1

Hey all,

Just started using OpenWRT on my 8GB Raspberry Pi with 64gb micro sd card and my experiences have been amazing so far with a few small issues here and there. Hopefully I'll be able to iron them out here on this forum.

My first issue is, I want to switch the functions of the ethernet ports. The 1Gbps ethernet port of Raspberry Pi 5 is connected to my mesh router and I bought a USB 3.0 to 2.5Gbps ethernet dongle (based on RTL8156) which is connected to the fiber internet ONT device. I set it up using PPPoE and can successfully get IP from my ISP and connect to the internet.

The thing is, by default OpenWRT uses Pi 5's 1Gbps ethernet. So I have to use that to connect Raspberry Pi 5 to my mesh router so that I can configure everything. Then I have to connect 2.5Gbps ethernet to ONT device. But the ONT device only has 1Gbps ethernet port and I feel like 2.5Gbps ethernet dongle is wasted there. What I want is to connect Pi 5's 1Gbps ethernet port to ONT and 2.5Gbps port to mesh router (which also has 2.5G ethernet ports)

But I'm too noob to figure it out without breaking the whole network. Any help in that regard is appreciated. I can provide screenshots of my OpenWRT interface if needed.

[SOLVED by replacing eth0 with eth1]

The second issue i have is to be able to use all available space on my micro-sd card. Right now OpenWRT only utilizes like 98MB of the 64GB card. Is there any easy method to expand that filesystem on Windows? I've read some posts about this but all required access to a Linux machine which I don't.

Third issue is, I tried installing "Zapret" from here https://github.com/remittor/zapret-openwrt and then "luci-app-https-dns-proxy" to get rid of Deep Packet Inspection of my ISP. But had limited success. Discord is banned in my country. I tried and Discord app still can't access its servers. I managed to log in on the browser though. Can anybody tell me what's going on here?

Last but not least, I'm looking for a good solution to circumvent any censorship based on DNS and blocking ads as a bonus on the side is always good. Before installing OpenWRT, I was running Pi-hole, Pivpn and Unbound on this Raspberry Pi and it not only let me access all blocked websites but also removed ads and I was able to connect to it on the go using my phone. Can a similar thing be achieved on OpenWRT?

Zapret has own guide, first set up that

@remittor 's package should be very close to upstream.
Once you figure that out post new questions about adblocks, vpn at home etc.

RE the filesystem issue why not boot raspian from a thumbdrive and use it to increase the openwrt partition ?

I recommend you make a data partition at the end of the system partition. Just know that if the root partition size changes on the image you will lose the data partition.

If the partition is resized correctly no data will be lost
