danitool: This bug was fixed in snapshot versions https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=e08ef42b24f But the kernel patch still needs to be backported to 18.06 and 17.1 |

Device: Observa VH4032N (bcm63xx/smp)
Version: at least from 17.1 to 18.06.2
Steps to reproduce: under the default config connect two devices via wired LAN to the device, try to contact one device from the other one (a ping will suffice). Result: timeout/host unreachable. However, contact with the router works without any issues.
I have only tested this with wired LAN clients, not between WLAN clients or LAN to WLAN.
"Dirty fix": separate each LAN port into a VLAN (create a VLAN for each port) and bridge these VLAN interfaces with the LAN interface.
The corresponding part of /etc/config/network would look as follows:
config interface 'lan'
option type 'bridge'
option proto 'static'
option netmask '255.255.255.0'
option ip6assign '60'
option ifname 'eth0.1 eth0.2 eth0.3 eth0.4'
option ipaddr '192.168.1.1'
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '3 8t'
config switch_vlan
option device 'switch0'
option vlan '2'
option ports '2 8t'
config switch_vlan
option device 'switch0'
option vlan '3'
option ports '1 8t'
config switch_vlan
option device 'switch0'
option vlan '4'
option ports '0 8t'
