RB5009 Unable to ping LAN devices, and vice versa  [SOLVED]

Wed Jul 06, 2022 5:40 am

Configuration is a wired router connected to various switches and access points. I updated from RouterOS 7.2 something and now I cannot connect to the RB5009 via IP - only MAC address. Pinging out from the Mikrotik there is no response either. Interestingly all the devices connected to the network can still reach the internet.

I can't seem to figure out the issue here, could someone have a look at my config, and see if anything appears to be wrong? ether8 has the internet instead of ether1, which is the default.

Rather complex so will just look for obvious stuff.

(1) You have no vlans so I wouldnt set vlan-filtering=yes!
/interface bridge
add admin-mac=DC:2C:6E:40:F2:5B auto-mac=no comment=defconf \
ingress-filtering=no name=bridge vlan-filtering=yes

(2) Why is dhcp server disabled?
/ip dhcp-server
add address-pool=default-dhcp disabled=yes interface=bridge name=defconf

(3) Seems to be an incomplete entry?
/routing table
add fib name=""

(4) Your attempt to mix ppp and wireguard is very confusing and using similiar names for things
also confusing vpn/VPN.

(5) Why do you have two addresses assigned to the bridge......
/ip address
add address=192.168.88.1/24 comment=defconf disabled=yes interface=bridge \
network=192.168.88.0
add address=192.168.89.1/24 comment=defconf interface=VPN network=\
192.168.89.0
add address=192.168.1.1/24 interface=bridge network=192.168.1.0

SUMMARY, config is a big jumbled mess that I cannot make heads or tails of. Didnt see anything that would solve your issue.

Thank you for looking at this. Agreed that this configuration is messy, but this is a hobby for me.

1) Noted, and have disabled it. The problem persists.

2) I have a raspberry pi that handles DNS and DHCP for the network so that is why DHCP is disabled.

3) I haven't made any changes here that I recall. Is possible something got messed up in an update? What should this section typically look like for a home router?

4) I had been using a L2TP/IPSec tunnel, which stopped working a while back because of a windows update. I had disabled the settings related to that and moved to wireguard.

5) That 192.168.88.1 line is disabled. I left most default config items, and just disabled ones I didn't need.

Correction - the pings are being responded to, but the reply from the Mikrotik's address is "Destination host unreachable."

Disabling the last mangle rule appears to fix it. To be honest I don't remember what the purpose of it was.
