UPDATE: 2023-10-28
Looks like laptop gets very low Rx rate (throughput from haru to Morgana) of ~17Mbit or even 6Mbit:

Config changes:
- Set max power to 30dBm
- channel switched to 5 (was 6): 15-25 on morgana and 13 on futaba
- channel 11: 10 to 25 on moragna, 16 on futaba
- channel switched to 5 (was 6): 15-25 on morgana and 13 on futaba
- Setting region to IE(!):
- 95/95 morgana -> justine over Haru channel 52
- BINGO!: 92/92 on MGMT channel 11
- This get me to 100Mbit; but I get much higher rates reported for wifi like 866/780 Mbit on Haru
- eth0 on Speed: 100Mb/s!
- Looks like faulty cable but I also rebooted Haru so could be that as well, although on secondary port I was getting 1Gbit with laptop before restart.
- goro reports only lan8 (haru) at 100Mbit/s but others at 1Gbit

- Looks like faulty cable but I also rebooted Haru so could be that as well, although on secondary port I was getting 1Gbit with laptop before restart.
UPDATE: 2023-11-05
There was a packet drop between Haru and Goro. I have replaced the cable that goes from Goro to power supply (for Haru).
After replacing the cable link dropped to 100Mbps, reconnecting it got me 1Gbit.
I have also switched channels for 5GHz radio to use:
- channel: 104 (5520MHz)
- width: 160MHz
Now everything is very fast. In kitchen I got 356/407 Mbps using Haru!
UPDATE: 2023-11-11
After power issue the network went up in bad state.
I was getting 300Mbit one way and only 46Mbit and high packet loss the other way.
I decided to route another cable to Haru.
Looks like Primary interface is the only one that can take power so I left it connected to the power supply but disconnected it from the swich.
New, longer cable now connects switch to Haru Secondary port which is part of a bridge setup with Primary port so no configuration changes was needed.
Now I am getting up from Morgana in kitchen 657Mbit and down 334Mbit from Justine.
DHCP no responses, no IP assigned
Looks like Graphene OS uses random MAC for every connection attempt to Haru:

To clean up the pool SSH to Caroline:
service dnsmasq stop
mv /tmp/dhcp.leases /tmp/dhcp.leases.bac
service dnsmasq startTo mitigate the issue I have reduced leas time from 30 days to 24 hours.
VPN clients coming from outside are NAT'ed
They will looks like justine, not their actual VPN IP, since devices can use caroline as their default G/W.
No access to SERVER VLAN from HOME with justine G/W
VPN clients can access justine MGMT interface IP
11:06:10.811023 vpn In IP 172.17.1.10 > 192.168.100.2: ICMP echo request, id 44951, seq 814, length 64
11:06:10.811041 vpn Out IP 192.168.100.2 > 172.17.1.10: ICMP echo reply, id 44951, seq 814, length 64I have set up more strict forwarding rules:
Chain FORWARD (policy DROP 52 packets, 4368 bytes)
num pkts bytes target prot opt in out source destination
9 35 5441 ACCEPT all -- enp1s0 vpn 192.168.0.0/24 0.0.0.0/0
10 32 5244 ACCEPT all -- vpn enp1s0 0.0.0.0/0 192.168.0.0/24but this does not help.
This is because it is not going through FORWARD but through INPUT:
iptables -A INPUT -i vpn -d 192.168.100.0/24 -j LOG[604557.640819] IN=vpn OUT= MAC= SRC=172.17.1.10 DST=192.168.100.2 LEN=84 TOS=0x00 PREC=0x00 TTL=64 ID=56812 DF PROTO=ICMP TYPE=8 CODE=0 ID=44951 SEQ=1064Adding the above rule will block it. But is this normal that any IP assigned to any interface can be used when routing to a G/W?
FIXED: I have added the following rule:
iptables -A INPUT ! -i mgmt -d 192.168.100.0/24 -j DROPFOLLOWUP: Is this the same for other devices? Try static route to them and access MGMT IP.
ip route add 192.168.100.50 via 192.168.0.50 dev wlan0And it will ping on 192.168.100.50. So services bound only to 192.168.100.50 will be exposed to HOME VLAN devices.
CONCLUSION: Binding to selected IP address does not protect service from being accessed from another network interface without extra firewall rule to prevent this!
What makes localhost (lo) interface special - services bound to it are not accessible from other interfaces? It has local routing tables set up by default.
Same problem for caroline
Same with caroline:
ip route add 192.168.100.1 via 192.168.0.1 dev wlan0I can now access https://192.168.100.1/cgi-bin/luci/ while on HOME VLAN, probably will work form SERVER and any other as well!
FIXED: DROP all INPUT on all interfaces apart from MGMT. Added ACCEPT rules for LAN, GUEST and SERVER VLANs for DHCP (UDP 67), DNS (TCP/UDP: 53) and ICMP.
I could not use the negative interface setup as in case of justine. Probably should use default INPUT DROP on justine as well and only allow mgmt interface traffic as well.
Would this be same for goro and haru?
They don't have IP on HOME network but they have interface. Injecting packet for MGMT IP to their HOME interface may be (using MAC/ARP) possible but they would not respond since they have no routing to HOME network?
Access to web services from internal network
Need to manually add static route for devices using default DHCP G/W (justine) when going to local server services like video.hexadust.net.
ip route add 46.7.126.16 dev eth0 via 192.168.0.1
ping video.hexadust.netThings to try:
- Try to push static routes from DHCP - this did not work for some reason
- Set up static route on justine
- Set up SNAT on justnie
- Use bridge layer DNAT: https://ebtables.netfilter.org/br_fw_ia/br_fw_ia.html
- Set up split DNS
video.hexadust.net 192.168.50.159- This would require justine to forward to SERVER VLAN since ann uses 0.2 as default G/W
- Set up separate DNS for internal access
No more IPs on DHCP
Looks like Horizon box eats up leases: https://www.boards.ie/discussion/2057720465/my-new-virgin-media-stb-issued-two-lan-i-ps
I have removed leases from /var/lib/dhcp.lease file on caroline.
Justine access is laggy; DNS is slow
Happens after OpenWRT updates.
Try disconnecting and connecting network cables for Haru and uplink on goro.
UPDATE: 2023-11-05: I have replaced both cables that connect Haru and Goro. The link tends to drop to 100Mbit if Goro end is disconnected, reconnecting fixes it.
Igor does not set it's default route after boot
While it is configured in web UI it is not taking effect on boot and results in it unable to find local network. VMs stuff will work OK though.
TODO
YunoHost access to internet via default IP instead of VPN
Not good for IRC etc.
- Clone the VM and put copy in HOME VLAN, remove public web stuff from it, remove web clients from SERVER VLAN one.
- Better yet. Create DMZ VLAN that has only access to Caroline and will run `www` server. Use SERVER VLAN to only have access to Justine, so out traffic goes out of the VPN, add interface to YunoHost that is in DMZ VLAN so that it can get requests from www server, but have it default G/W to use Justine over DMZ?
- Create SANDBOX VLAN that only has access to justine as G/W.
- Create VM that connects to Justinve via WireGuard and pit it in HOME network and in virtual network that it will be G/W for, put other VMs in that sandbox virtual network.
- Create VM that uses SERVER VLAN to make connection to Mullvad (dedicated key) and act as a G/W for sandbox virtual network for other VMs.
24/09: WWW access very slow
Downloading file from www server (Caddy) is slow.
Phone over 5G with VPN (to justine): ~1-2 MB/s
Phone over Haru with VPN: ~2-3 MB/s
From laptop (VPN + Mullvad): ~3 MB/s [NOTE: Even using local SERVER IP it goes over Mullvad IP!]

Requests to kernel.org are fine.
Requests from sanbox-gw are also slow - they go via Mullvad that is deployed on sandbox-gw (not via justine):

Using local route to go directly to caroline does fix the issue, so going through the internet is where the slowdown happens.
ip route add 46.7.126.16 dev wlp52s0 via 192.168.0.1Things to try:
- Change VPN exit node
- Try access from non-VPN connection
Fast.com (over VPN) shows 300Mbit down and 1.2 Mbit up - this explains slow download from the server (as it is upload to the internet). Without VPN I get 300Mbit / 48Mbit - so the slow down is due to VPN.
