Uploading to remote site failing when using subnet router

At my local site I've got a Proxmox server (10.10.18.198) running various stuff including Tailscale in a LXC (10.10.18.102), and I've got a remote Proxmox server (10.10.55.198) running Tailscale in a LXC (10.10.55.102) and Immich in a LXC (10.10.55.209).

On my OPNsense router at the local site I've got a route to send traffic for 10.10.55.0/24 to my local Tailscale LXC. At the remote site the OpenWRT router has a route to send traffic for 10.10.18.0/24 to the remote Tailscale LXC at 10.10.55.102.

That generally works OK and I can access the Proxmox Web UI on 10.10.55.198 from my PC (10.10.18.64), but if I open the Immich Web UI and try to upload a photo, it creates the file on the remote server but the progress bar gets stuck around 50% and after a while it fails and deletes the incomplete file. It seems that the upload always stop around 64 KiB, even though the progress bar suggests that 700 KiB have been uploaded.

If I install Wireguard in the remote Immich LXC and add it as a peer in OPNsense and use the Wireguard address to access the Web UI, so the traffic is going from my PC to OPNsense and then straight to the remote Immich LXC, the uploads work fine. They also work if I connect my PC to Tailscale, so the traffic is going from my PC to the remote Tailscale LXC and on to the Immich LXC.

It's only not working when I'm using the subnet routing, where the traffic goes from my PC to my OPNsense router, then to the local Tailscale LXC, then to the remote Tailscale LXC and on to the Immich LXC MSS clamping in the local Tailscale LXC doesn't make any difference.

Has anyone found a fix for this?

Need a dropper for ULDN

I've got a 100ml/100mg bottle of Naltrexone and a 1ml syringe is fine for 1mg but I want to try lower doses like 0.1-0.2mg which isn't possible with the syringe.

​

Is there a dropper I can get that will give 0.1ml per drop, so I can syringe about 0.5ml into something like a shot glass and then use the dropper to take 0.1mg?

Signal seems weak with Sonoff Zigbee 3.0 dongle

I live in a small flat and the Sonoff dongle is connected to my SFF PC with a USB extension cable and sitting on top of my rack in the corner of the lounge, right next to the wall between the lounge and the kitchen which is about 50% glass. In the kitchen I've got a Third Reality UZ1 smart plug behind the fridge about 6ft from the dongle and that reads 120 lqi in Zigbee2MQTT (probably not surprising as it's got a big metal box in front of it), and a Sonoff SNZB-02LD thermometer on top of the fridge which reads 189 lqi.

I've also got a SNZB-04PR2 window sensor sitting about a foot from the dongle which reads 178 lqi and two more UZ1 smart plugs in the lounge which read 185 lqi and 163 lqi respectively (the former is at the other end of the room to the dongle and on the floor behind the end of the sofa, whilst the latter is plugged into the wall and has a line of sight to the dongle so I would have expected it to have a stronger signal).

Zigbee Map shows that the UZ1 behind the fridge and the SNZB-02LD thermometer on top of the fridge aren't connected to each other, with the latter only connected to the dongle and the UZ1 connected to the dongle and the other two UZ1s, and the SNZB-04PR2 window sensor right next to the dongle isn't connected to it, only to the UZ1 at the other end of the room on the floor.

I'm a bit disappointed as other people seem to get readings in the 240-250s. I was thinking of setting my Dad up with the same dongle and devices in his 2-storey house but I'm skeptical that it would work now, as his HA PC is in the corner of the lounge/dining room under the TV and whilst I'm sure it will work fine with any devices in that room, I doubt any devices upstairs would be seen by the downstairs ones or the dongle. There isn't really anywhere in the downstairs hall to plug in a smart plug to act as a relay between upstairs and downstairs either. At the moment he has a few WiFi smart plugs in the lounge and they connect to the router upstairs in the box room at the back of the house fine. So is Zigbee a worse option than WiFi for houses?

I've been using this guide to help me setup i2pzero https://www.coincashew.com/coins/overview-xmr/guide-or-how-to-run-a-full-node#optional-setup-i2p

There's a few obvious mistakes, like it tells you to chown stuff to the i2p user before creating that user and then further down the page it tells you to cd $HOME/i2p-zero-linux when that doesn't exist and the files are actually in /usr/local/bin/router, but it got me half-way there.

Then I looked at this https://github.com/i2p-zero/i2p-zero/blob/master/monerod-with-i2p-zero.md and it says to run i2p-zero but that gives me:

Error: could not find libjava.so
Error: Could not find Java SE Runtime Environment.

So I did "apt-get install default-jre" which installed about 650MB of files and "java -version" shows:

openjdk version "21.0.10" 2026-01-20
OpenJDK Runtime Environment (build 21.0.10+7-Debian-1deb13u1)
OpenJDK 64-Bit Server VM (build 21.0.10+7-Debian-1deb13u1, mixed mode, sharing)

but I still get the same error when trying to run i2p-zero.

What do I need to do to get this working?

I sent a transaction about 22 minutes ago but it failed because my node was down. Now it's up and synced but when I try to do another transaction it gives me an error about double-spend, so how long will it take before it allows me to do another transaction?

EDIT: The error is "Couldn't send the money: transaction ... was rejected by daemon with status: Failed. Reason: double spend".

My node conf is below. I haven't port forwarded the ports on my firewall yet or setup i2p, so it's only accessible from the LAN at the moment and Monero GUI is connected to it and synced.
