+Before doing the docker compose up always use the command  
+
+1) Create a macvlan network for the containers
+
+Pick a tiny slice of your LAN that you won’t use for normal devices; we’ll use .200–.206.
+
+# stop your current containers first
+docker compose down
+
+# create the macvlan network (parent is your NIC that’s on 192.168.10.0/24)
+# \\ here remember that you have to set the subnet gateway ip-range and the parent with your network configuration 
+docker network create -d macvlan \  
+  --subnet=192.168.10.0/24 \
+  --gateway=192.168.10.1 \
+  --ip-range=192.168.10.200/29 \
+  -o parent=enp6s0 \
+  ad_vlan
+Why: macvlan lets each container appear as its own L2 host on your 192.168.10.0/24.
+
+2) Allow the host to talk to macvlan endpoints (host-access workaround)
+
+macvlan blocks host↔︎container by design. Create a macvlan sub-interface on the host so Arch can reach them:
+
+# create a host-side macvlan interface that shares the same parent
+sudo ip link add adhost link enp6s0 type macvlan mode bridge
+sudo ip addr add 192.168.10.9/24 dev adhost
+sudo ip link set adhost up
+
+# route the small pool via this host-side macvlan interface
+sudo ip route add 192.168.10.200/29 dev adhost
+
+Now your Arch host (192.168.10.10) can reach the macvlan IPs through adhost (192.168.10.9).
